Im feel like im going crazy

Im 39F

I'm in a serious relationship. My prior relationship I was in an abusive relationship, I had my children at a very young age.

With that being said, I been with my boyfriend/fiancé/ husband what ever you may call it for 10 years.

I feel like ever since we moved in I've been trying to be miss perfect for him. My kids and I had a strained relationship because maybe of him he doesnt think he did anything worng.

Anyhow he's been on a business trip for the past 6 months.

It seems like we've been fighting every weekend I feel like he's only happy if im doing activities with his family.

Every time I go to my kids house it's like he gets annoyed.

Lately our communication has been horrible. We pick a fight over dumb shit.

I recently started school and this homework ain't no joke. I feel like im stuck in front of this computer for hours!!!

I don't post my my socials because I feel like im being watch.

I don't have a social life because I don't want to cause any more arguments. I don't have friends outside of work (sad) i keep myself busy with my kids sports because I feel like that my moment to shine, make up hair done .. i mean I think I clean up good. I don't post any selfie because I won't hear the end of it.

I recently started talking to a therapist because I feel like I have some sort of ADHD, anxiety, depression, all of the above. She said I have PTSD, and im bipolar 2! Im borderline depressed, and i hsve borderline anxiety, Wtf how? I thought i was going through "my life changed"

Anyhow I cant do this anymore I. Feel like I want to rip my own skin off, run away, go off on someone. I cant focus on my schooling. I just want to scream i hate it here. I want to get away and never come back. I don't know what time do.

Sorry for my typos and my rant I just feel like maybe just maybe im not the only one feeling like this. Im not stupid to harm myself or anyone. Idk I just told him to leave e alone not to call me no more because I was done! Wtf do I do?
