My mom has BPD. My brother has childhood PTSD. 

My mom is not medicated or in therapy and has refused treatment. Their relationship is completely broken. He blames her for his PTSD, feels he has been manipulated his whole life. She does not take responsibility. I'm his sister and feel so stuck between this. They both had a mental break this week. My brother is in the hospital for suicidal thoughts today. She sees her doctor tomorrow and my dad is going with her to keep her honest about the treatment she needs. She was in a manic state this week after my dad found a warrant for her arrest she has been hiding for 3 years. Drunken disorderly conduct. She says it just didn't happen.

I hope this is the right community to talk to. I find all of this so confusing. I don't know who to call and check with. They're both freaking out about the other. I think the hardest part is that my mom is not in the same reality. She doesn't have a warrant, her son does not have PTSD, she doesn't have BPD, and everyone is ganging up on her for no reason. I can't take the lies anymore. I don't even know what's at the heart of their issues together, my brother can't even talk about it. He's gone non verbal in the hospital.
