No where to walk?lol you have the whole world to walk on.
To brake your lonliness go out and socialize more often.If you really want to find someone you will find a place regardless of how far it is.
For your work related stress find another job if you hate it.It is not worth getting ill and loosing years from your life span.The more frequent the stress is the higher the chance of getting ill and the shorter your life span will be.Think about if your job is really worth loosing your life and your good health.
You are doing this to yourself.You alone are responsible for your situation.No one is forcing you to work there.
For your depression apply the following recipe.
Depression is caused by the lack of serotonin in your brain which is caused by the lack of omega 3 fatty acids in your brain.A deficiency that most of the humans on this planet have.
Omega 3 fatty acids raise your serotonin levels.The more you have the better you feel among many other benefits.
Start the omega 3 diet.I have researched omega 3 acids for 2 years and performed a very successful experiment on myself and few of my volunteer friends.Few months of the omega 3 diet it significantly reduced stress[and/or cured depression] problems permanently and significantly raised my intelligence,improved memory,gave me high emotional and muscle control,sight,reflexes[and many other known and unknown benefits]and without any drugs or supplements in the form of pills.

Take two table spoons of grinded flaxseed[rich with omega 3 and cheap]a day[with a glass of water] and in a few months you will start to notice significant improvement in your mental health[you will become more psychologically stable,among other things].Use a coffee grinder.Whole seeds cannot be digested by the hydrochloric acid in our stomach only grinded seeds.A fact and not a assumption.You have nothing to loose only gain by it.There are many articles on the internet about the omega 3 fatty acids.
Flax is the best source of ALA omega 3 fatty acid which our body converts to more important fatty acids called DHA and EPA.For the efficient conversion to take place,foods containing a large amount of the following nutrients must be consumed along with the flaxseed:C,B3,B6 [vitamins],zink and Magnesium [minerals].I recommend 3 table spoons of flax with 100 grams[or more if to your liking] of almonds and/or 250g of green peas,1 kiwi every day.[do not take more then 3 table spoons of flax because large amounts can cause intestinal gases which can cause abdominal pain and/or constipation.If three spoons causes abdominal discomfort lower the dosage to 2 table spoons of grinded flax and elevate it to 3 table spoons after your body adapts to high fiber content].
