so depressed and stressed

im 18. i am 25 weeks pregnant and well my mom doesn’t help me at all, i know it’s not her baby & she isn’t obligated to help me. the thing is i was trying to find a job applying everywhere & she was constantly stressing me out telling me how i haven’t done anything for my son. Her reasoning for not helping me at all was because when she was pregnant she did everything “on her own, never asked her parents for help” although she was 22 and has 8 older siblings to help her out. im only 18 and no support system but He has a crib, a little baby bouncer, a couple bottles i bought and a few clothes.. and now everything got to the point where i moved in with the baby’s dad because she’s way too toxic for me. she’s always been bad for me but being pregnant stressed me out even more. I’ve become very depressed because my baby’s dad and i were breaking up because he’s cheated on me and wouldn’t stop talking to girls and i didn’t want to put up with that anymore but this whole situation pushed me to move in with him continue my search for a job and i havent spoke to my mom in a month & half. i just feel like i have nothing. no where to go. i want to go back home bc i dont want to be somewhere where im stressing about if he’s still talking to females or not but i just cant go back home cus id have to restart my job search and have my mom constantly trying to argue and pick at me. im only 18 with no car and she doesn’t understand i need help.
