Welcome to HealingWell. I am sorry to read that you are right in the middles of what appears to be a dysfunctional family situation.
Couple of things that came to mind as I read your post. Nobody can make you feel responsible or guilty for somebody elses's behavior. It sounds like your Mom has been having an ongoing situation with the 3 of you for years and fighting is not the answer for you.
May I kindly suggest you rethink what you want to do with your life as right now you seem to be trying to solve and/or cure the rest of your family. Removing yourself from the family dynamics is my best advice for you. Your situation right now feels very unhealthy to me and I am concerned about you.
Give yourself permission to set strong boundaries and then distance yourself from all of this mental turmoil.
I have been in the middle of family situations that would end up with me in high anxiety mode and worrying about everybody or trying to fix them. I have a mantra now that I repeat in my head when I'm with them. 'this is not my issue, nothing I do will help anyways, and say nothing". Now I sit back as an observer and although this new role confuses them, I just shrug and relax. Annoying things don't bother me much (or for long) anymore because I have disassociated myself from the scenerios.
I hope you can find peace in your life and remember to take care of you first.
Kindly,
Kitt
