You're right, your deranged preoccupation with mental illness is telling. Tonight I'm gonna have a bacon-cheese burger. I am neither Jew, Muslim, or Indian. If I did decide to become superstitious, I would become Christian, as it is my heritage and culture.
Here is something that should help you a lot:
MENTAL PROBLEMS -- A SELF-HELP GUIDE
(1) Avoid as far as you can the use of psychotropic drugs such as tranquilizers and anti-depressants for these only mask your problems instead of eliminating them. Besides, they can be counter-productive in the long run.
(2) Stop the consumption of junk foods and drinks.
(3) Eat only whole, organic foods that contain complex carbo-hydrates.
(4) Eat five or six small meals a day instead of only three or less.
(5) Drink plenty of good quality water.
(6) Do experiments on yourself to find out if there are any foods that affect your mood, foods to which you might be allergic.
(7) Do some physical exercise every day for at least half an hour or take up some sport such as tennis, basket ball or squash.
(8) Listen every day to some music that you like.
(9) Find or think about something every day that would make you laugh.
(10) If you smoke, try to give it up.
(11) Whatever you may be going through, don't ever blame yourself for what you might or might not have done in your life.
(12) If despite all the above, you still feel that you ought to see a therapist, go to someone who specializes in Behaviour Therapy. It is about the only therapy that is based on scientific research. The following two sites on this therapy are easily understood by laymen, especially the second one which is a fictional case study, something you are likely to relate to.
Hope sincerely it will help you somehow.
