I feel alone

I have a 10 month old daughter and I am a stay-at-home mom...My boyfriend and I live with my parents and we have our own guest room. My boyfriend has frequently been putting me down and it is starting to send me into depression. My postpartum journey has not been easy so I am having a hard time finding my identity again. I do not feel like myself and I miss being happy. I do not blame my daughter at all, I love her so much. My boyfriend does not understand what I am going through and compares me to others. "I know there are moms out there that do way more than you." "You should go get a job and stop being lazy." "All you do is take care of our daughter, that's it." "All you want to do is sleep when our daughter is taking a nap." I went to college and got my Bachelors degree in Liberal Studies and I just need to get my teaching credential but I have my career on pause because I want to focus on my daughter and make her my priority right now. My boyfriend tells me, "Look at you now, not doing anything with your degree. You are just using our daughter as an excuse to not get a job." All of these things that he is telling me is starting to affect me mentally. Crying myself to sleep because I feel not good enough. He tells me how he is unhappy in our relationship and threatens me to take me to court to get full custody over our daughter. If we were to separate, he would have to move back to his parent's home....His mother is an alcoholic, his father drinks and does cocaine, and his sister is always high from marijuana. That environment is not the best environment for our daughter to live in and I am afraid of my boyfriend getting full custody. My boyfriend has a past history of drug use but he has been clean for a year now. I would overall be happy if I were not with my boyfriend and just had my daughter all to myself. I am thinking of doing individual therapy sessions so I can better my mental health.
