First of all - I believe you and know how difficult your situation can be.
It would be helpful to know how old you are - I realize that if you are still under the roof of your parents and a minor - under 18 - then it can be incredibly difficult. Your problem is evidently intensified in terms of how you feel - due to the fact that those who are close to you do not accept yor 'illness' is real. This is common.
I do not know why you find your Doctor so unhelpful - but I am not surprised. During the last 3 years that I have been struggling with a bout of depression I have been lucky to have an understanding and helpful doctor - but I went through several befre I found someone who had the right empathy and offered support that has been helpful.
OK Daisy - I just did a quick check - and saw your post of 2 weeks back - now I see you are 16, and have additional issues that are bound to contribute to your depression. I can't tell where you live - so any advice can only be generalized - as I guess I know more about UK services than US.
It is a shame that the 'medical professionals' you have seen have done all the usual stuff and just given you a variety of chemical stuff to try and 'treat' the problem. If you have had acne problems since 8 years old then there is evidently a problem that needs resolving. This could be to do with diet or other exposure to synthetic chemicals in your day to day environment (there is an item at www.gonando.com I will link at the end of this response).
Ropaccutane is a strong treatment which is normally prescribed for difficult acne cases - but it does have side effcts - here is a quote from on credible web resource:
[QUOTE]
"...Isotretinoin can have serious side effects and its use must be supervised by a dermatologist. It is reserved for the treatment of severe acne (such as nodular or conglobate acne or acne at risk of permanent scarring) that has not improved with standard treatment involving oral antibiotics and topical medicines.
Your acne may worsen at the start of treatment, but this usually subsides within 7 to 10 days of continued treatment. In most cases, complete or near-complete clearing of acne is achieved with a 12 to 16 week course of treatment, and you are likely to remain free of acne for a long time. Repeat courses are not normally recommended, unless a definite relapse is seen after treatment is stopped. Repeat courses should not be started until at least eight weeks after stopping treatment, as your acne may still improve in this time."
MORE IMPORTANTLY the massive range of side effects are pretty awful (I guess you may have read the medicine leaflet but the resource above also includes this list of info - NOTE: Depression is a potential SIDE EFFECT read down the list:

"Warning!
Isotretinoin causes major birth defects (serious malformations of a developing foetus) if taken during pregnancy. For this reason your doctor will not prescribe the treatment to women who could get pregnant, unless the following criteria are met: At least one, but preferably two (for example the pill and condoms), effective methods of contraception must be used at all times to prevent pregnancy. Contraception must start at least four weeks before starting treatment, be used at all times during treatment and for at least four weeks after stopping treatment, even if you don't have a period. Your doctor cannot prescribe isotretinoin until you have been using effective contraception for at least a month and have had a negative pregnancy test. Your doctor is only allowed to prescribe 30 days supply of isotretinoin at a time. You will need to have a follow-up visit every month, at which you will have to have a negative pregnancy test before a new prescription can be issued. Five weeks after stopping treatment you should have a final pregnancy test to make sure you have not fallen pregnant. If you think there is a chance you could be pregnant, either during treatment, or in the first month after stopping treatment, you must consult your doctor immediately.
There is no evidence to suggest that children fathered by men who are taking isotretinoin will be affected by the medicine, but men should remember not to give this medicine to anyone, particularly females.
You should never give this medicine to another person and you should return any unused medicine to your pharmacist at the end of treatment.
People taking this medicine must not donate blood during treatment, and for at least four weeks after stopping treatment. This is due to the potential risk of the medicine to an unborn child if the blood transfusion was received by a pregnant woman.
This medicine may cause depression, anxiety, mood changes, psychotic symptoms and rarely suicide attempts. For this reason, if you start to feel depressed, or experience any other mood changes during treatment, it is important to talk to your doctor.
You should avoid exposing your skin to intense sunlight or UV light while taking this medicine. You should use a sunscreen of at least SPF 15 when necessary.
Isotretinoin is likely to make your skin and lips very dry, so it is recommended that you use a moisturiser and lip balm from the start of treatment.
You should avoid waxing any part of your body while taking isotretinoin, and for at least six months after stopping treatment, as this could cause stripping of the top layer of skin. Chemical dermabrasion and cutaneous laser treatment should also be avoided during treatment with isotretinoin and for five to six months after stopping treatment, as this could cause scarring.
Isotretinoin can make your eyes dry. This can be relieved with artificial tear drops. Ask your doctor or pharmacist for advice. If you wear contact lenses you may find that they become uncomfortable during treatment and you have to wear glasses instead. Decreased night vision may also occur during treatment and after treatment has been stopped, and can occur suddenly. For this reason you are advised to be cautious when driving or operating any vehicle at night. If you experience any visual difficulties, inform your doctor so that your vision can be monitored. It may sometimes be necessary to stop treatment.
You will need to have a blood test to monitor your liver function before you start treatment with this medicine, one month after starting and then at further three-monthly intervals.
The amount of lipids (fats such as cholesterol) in your blood should also be monitored before treatment, one month after starting treatment and at three-monthly intervals. If your blood level of triglycerides becomes too high, your isotretinoin dose may need to be reduced and you may have to go on a low fat diet. If your triglycerides cannot be controlled, you may have to stop treatment with isotretinoin.
This medicine may increase your blood sugar level. People with diabetes may need to monitor their blood sugar more frequently during treatment with this medicine. Ask your doctor for advice.
If you experience severe bloody diarrhoea during treatment with this medicine you should stop taking it and consult your doctor immediately.
This medicine is not recommended for children under 12 years of age."

THIS MEANS you may well be unsuited to this medication - especially if struggling with undiagnosed/untreated depression up til taking this medicine - which is evidentally making things worse. ADDED - AS ADVISED ABOVE YOU MUST TALK TO YOUR DOCTOR ABOUT THE PROBLEM IF YOU ARE STILL ON ROACCUTANE. SHOW YOUR MUM THE MEDICINAL SIDE EFFECT INFORMATION.
There is also an articcle at http://www.gonando.com about acne - which gives a simple program that could help at least to provide some ideas about whether or not you are currently doing all you can to avoid making your acne worse.
You DEFINITELY need to find someone to talk to - and if you confirm your location (US, UK or other - country only if you prefer, State or County would be helpful - I will add further advice here or via email.
