Sooo unhappy am I the only one?

Cassandra

So I'm 10 weeks preg with my 5th. Idk how I feel about it. Been a single mom for 2 yrs after an 8 yr marriage now in a relationship with a guy with 2 sons he has custody of. They annoy me so bad they don't listen to nothing and if their not on some kind Xbox or game their hell. They have had no mother in their life so they don't respect me at all. And my bf don't back me up on any rules and thinks I'm too strict and I need to give a lil. I'm so over it that I'm over the relationship even. I'm mad that he talked me into getting preg and I'm so sick that I can't work. Even looking at him makes me mad. My kids r even unhappy cuz his walk all over mine. I tired I don't wanna be touched or even spoke to. We have only been together 5 months but have known each old for yrs. Idk what to do and my sister is so over hearing how I feel about all this. I feel so alone. So depressed and off my bi polor meds I just wanna lay and cry. Somebody please help me what do y'all think. I look at him and I'm just so not attracted to him I want nothing sexually to do with him all I can think is just plz get outa my house. :(
