Welcome to PC!
It sounds like you're going through so much right now, and you shouldn't have to go through it alone.
I agree with Wimsy's suggestion about finding counseling. I just moved within the last few months, and finally found a therapist this past week, and already it's making a difference. Just someone totally caring to help you sort things out can mean so much.
You could also call a local domestic violence hotline, they're trained to help you talk through your situation and can point you towards resources.
Also, search in your local area for any kind of free support group. They have them sometimes for women in general, or for those with depression, ETC. This might also help.
If you need help looking, I'm great at this kind of thing so just PM me with your general location and I'll see what I can come up with.
