I'm sorry that your situation is so hard. You need more moral support. Like the poster above, I hope you have someone trustworthy to talk to. In the meantime, we are here also. Each of the stressors you mention is a big topic all on its own. Eventually, I would encourage you to start a thread for each of them. I suggest that because here at PC you probably can get feedback from others who have had each of those tough things to deal with. You might feel less alone with that input.

To have all those stressors going on must feel overwhelming. You truly are very depressed. It can seem impossible to change things, but that is the depression talking. Your life is as important as anyone else's. You have worth, and there are people in this world who will value you . . . as we here at PC value you.
