Depression lead to postpartum depression ?

I have a few weeks left in the pregnancy and I am not even happy. I feel myself depressed and not scared it will lead to postpartum depression. I have never had it in my previous pregnancies.

I’m stuck in a marriage for now. He’s an absolute monster. I have lost my family and friends because of him. My mom gave him another chance. He recently asked her to leave his house because we were having an argument. (She was staying with us for a few days). He yelled at me, he talked to me like a child in front of her. She did leave and said she’s not coming back. Now I have no one to watch my 14 month old while I give birth.

I’ve also been off work since jan. He works at night, sleeps all day, wakes up to go to the gym for 2 hours then back to work. He does not help me at all with anything. I can barely move but he expects me to cook his special dishes for his “gains.” I’m exhausted. And mentally drained from his verbal and emotional abuse. He has no problem being physically abusive. When we argued, he threw a diaper at the back of my head. Never apologized. Always talks about my mom. I honestly don’t want her here to feel disrespected.

I have nowhere to go. I don’t know how or when but I know I need to leave this marriage. I just cry all day. I pray God shows me the way because I can’t see it right now.
