Need Help

I don't know what to do. I've suffered with depression almost my whole life. My daughter is almost 2 months old, and things have gotten worse. I was really sick when I got pregnant and lost my job and my apartment. I considered abortion and adoption because I knew I wouldn't be able to provide for her. I packed up and moved 1000 miles back home to my parents to be on bed rest and eventually have a 32 week preemie. She's only been home from the hospital for about 2 weeks (after being there over a month). My mom and I have never gotten along, and this has been an even bigger strain on our "relationship." I hear her saying negative things about me to my dad all the time. She lies about how much involvement I have with the baby and always tells me I'm doing everything wrong..or just disagrees with me in general about everything. Sometimes, she'll pass my "bad" ideas off as her own then claim they were hers. I know I can't afford to move out anytime soon, and surely not be able to work full time with all the extra care and appointments my daughter needs because of her prematurity. A little while ago, I heard her tell my dad that she's done with it all. She's not helping me with anything anymore. I live their office on a day bed and have none of my stuff here. If I died in a "car wreck" tomorrow, whose loss would it be? I heard my mom say things would be easier if I wasn't here at all. I love my daughter so much, but I feel like there's nothing I can do. Every little bit of happiness I have gets zapped away by my parents, mainly my mom. I don't want her raised by them or by strangers if I put her up for adoption. I just know that I can't go on like this. I just really can't.
