As someone who has been there before, yes, there's hope. First, you need to go to another doctor.
Doctors in this country are very much now doing psychiatric work, and they all run in the same school of thought. It's likely the people that were referred are people that the doctor knows, and likely agrees with their method of treatment. And the cycle goes on.
Aside from going to a different doctor and getting a second opinion (which I can't stress enough - this is your health!), exercise and a change in diet is incredibly helpful.
Try walking for 5 minutes a day. Nothing strenuous. If you have the stamina, increase it when you feel like it. Also consider increased intake of varied fruits - one thing that really helped was cottage cheese and blackberries first thing in the morning with water. Those two things themselves did a huge turnaround, on top of an excellent support from a psychiatrist and a very understanding doctor.
To give you an idea of how bad mine was, after three years of dating I proposed to my girlfriend, I sobbed uncontrollably that night and didn't leave the house for several weeks. There was a long bout of untreated depression, and preparing to propose to her kept my mind off of my despair, but once I lost that crutch I completely lost it mentally.
It's not will power. It's a matter of resigning yourself to doing these small things.
As for me, I'm happily married, expecting my first child, and have been off the medication for a long while now.
There IS a light at the end of the tunnel. Don't feel pressured to do more than one or two things at once. You tackle that first thing, the rest comes naturally over time.
