It's so hard when parts have so many needs that weren't addressed or were abused when we were children. I'm so sorry this is so hard right now. One thing I try to do is make sure I give enough time to give parts time and opportunity to do things that are self soothing/nurturing. I may or may not remember the time spent, but I find it helpful regardless. It could be something as simple as putting on a nice movie or snuggling with a blanket to coloring, reading, going for a walk in nature, etc. It seems to help fulfill things that parts need.
Another thing I've done is try to broaden my support system. I think it's easier on people when they aren't your only support. Having a bunch of parts is hard, imo, because sometimes I feel like I never get support and yet find that "I" have been getting all sorts of support. I just don't have any memory of it. Having many sources of support really helps me to feel supported and helps the ones supporting me not to feel overwhelmed and/or burnt out from it.
If you are unable to go to a different AA meeting, can you at least try to broaden your supports there so that one person is not the only one supporting? Or what about going to several different meetings (if that is allowed) so that you have more support than one person. That way you can still keep the support from her that you have without anyone getting burnt out.
Good luck with your journey. We want to support you.
