Im really doubting my current relationship but have no clue what do to and feel trapped. My mental health is rapidly declining but i feel i cant leave as we have a baby on the way and am so scared of being shut out.

I walk on eggshells everyday knowing i do the slightest thing wrong its not a hey, can you do this, its an aggressive fucks sake or yells because i have forgotten to do one of the 6 tasks i have been asked to do at once while she sits on her phone. Now i get she is pregnant and im happy to help and do more but the way she goes about it has made me lose all confidence in myself as a human being

I know that she would struggle financially without me and thats a lot of whats keeping me around, but i can feel myself about to snap and thats when it will get ugly. Im a talker, when my feelings are hurt or if i dont agree i want to talk it out, but everytime i bring up how this all makes me feel i get told to stop being a bitch, or you done having a sook

Im lost and hurting and i just need someone to tell me if im thinking right or not.
