I feel so down

Arianna
I have struggled with anxiety and depression since I can remember . For a while in my pregnancy I was so happy, having a job I loved helped alot. Now at 33 weeks I was laid off a month ago , my fiance has to work 2 jobs to get us by and I feel like it's all my fault , I feel so guilty . Our relationship is not the same anymore , whenever he isn't working he is out all hours of the night with his friends coming home drunk at 5 am or not coming home at all . I am literally constantly alone almost 24/7. The only time I ever get out of the house is when we visit family . I don't have my own car so I can't really go do things , I have no girlfriends I can talk to, I have no one. I'm 23 and I feel like I'm a total failure , I never do anything right . My self esteem is just shit , I I want to cry when I look u at myself in the mirror. Im just so so lonely and I try so hard to stay positive, I'm just so scared I will be a bad mom. I'm so sick of being sad :( and I'm scared it's only going to get worse after birth .
