Eran,
I went through that 2 1/2 years ago. I could relate to eveything you mentioned but there is hope out there. I was jobless because of my breakdown, in serious debt and had no friends, very suicidal and had basically given up on life. Managed to find a job with very poor pay, got in even more debt, stopped eating to pay the bills and my life was just a big mess. 2 years ago I went bankrupt, had to wipe my debts off as I would not be here now if I didn't, I felt like a failure and very embarrassed about being bankrupt but looking back now that is the best thing that could have happened to me. I was able to stop stressing, turn my life around and now I can see a light at the end of the tunnel although it is way off in the distance. I have learnt alot from this. My problem was that when I got depressed I would go on a spending spree using credit and was unable to pay it off.
I believe things always happen for a reason and when they do and you overcome the hurdles in life you end up a better person in the end, I now hold down a fulltime job which I enjoy, I am debt free and slowly getting back on my feet financially, I'm working on trying to overcome my social phobia and all I need to do now is to stop isolating myself and to make some friends. If you want something bad enough you can make it happen.
