5 months pregnant and I’m soo depressed

I don’t know where else to express myself but lately I’ve been so depressed. I’m 22 and I was looking at pictures of how I used to look and stuff and I’m so depressed because I understand I’m pregnant but I’ve gained way to much . I have stretch marks all over . I used to be a gym freak and now i weigh 260 😭I let myself go I used to get my nails done and hair and I look homeless all the time . I m way to lazy I can even be the woman my bf deserves I feel like a failure n I’m scared I won’t be good enough for my baby I’m soooo exhausted as I’m the only one working and it’s barely to get by . I’m so depressed on how my life is right now . All my friends really don’t talk to me since I got pregnant and it’s because they’re to busy having fun without me . And sometimes I feel like my relationship is going downhill and I’m scared it’s not what I want anymore. I pictured everything so differently and now I struggle to even wanting to do anything . Definitely could be my emotions but my life sucks so much right now my man won’t even have sex with me mostly because he thinks of the baby but it makes me feel so rejected man. I would never regret my unborn daughter but I’m terrified to bring her in this world where it’s a very crazy scary place.
