Depression is bad..it takes away the will to do anything let alone live. Have you contacted your pdoc to see if you can get your meds increased? Sometimes its just about that, and getting you out of this bad depression. When you feel better you will thing differently.
I have been there, and so glad I did not do anything as the situation did change over time. I always like the quote "Don't give up before the miracle happens" It makes me realize that things do change if I allow it and can hold on!!!

I hope you feel better. Its not the world, or your environment, its how right now you perceive it.. Please hang in there. Its gonna change..really!!!
