I guess it's partly not feeling confident enough to confront those that lack in helping family members in need......and then there is a part of me that thinks I should just do what I feel is right and not let what others do, or don't do, bother me.......but within that, I just cannot feel comfortable around them, siblings or not......it would be nice to have real thick skin sometimes but I can't pretend it does not bother me.......I really never feel like "poor me", I do so much more, it's really about having sisters in my life, that I cannot stand being around, or have any love for.........it's a catch22 sometimes, where you wish you had a lovey dovey family and then realizing it's just not that way........I actually fear funerals, or places where I might run into them because I am the one that gets frustrated and sometimes angry at seeing them and then they act like I am the one that is wrong.........it would not bother me in the least, to never see them again and I don't really feel bad about that, I just wish I could come to some inner peace over the whole thing..........
Second, talking to a therapist about this sort of thing can bring great clarity, or at least it did for me. Most of us have leftover simmering sibling issues that rear up under the stress of dealing with elderly parents. Seeing a therapist might be a great investment in your own future.
Hang in there, you will be okay. Enjoy your life.
