My sister, whom I helped raise, has had multiple problems since her teens. She is aware but will not help herself or accept help from anyone else. I love her but we live in the same house(aging mother) and frequently being around my sister has gotten unbearable for me. I am 63 and she is 53. I've been married and all that jazz. She..never. Lived at home all her life and try as I might I have lost the ability to understand her. Our other sister, just 1 year older than the 53 died in 2011. We talked about the youngest and she told me she didn't understand her either. I'm hoping to find others in similar situations who may have some coping ideas. I'm not saying I'm perfectly sane either, but at least I can cope with life. Grateful for any comments, suggestions. We live in a rather backward area and I don't want to keep harping on this with my friends who are sympathetic but can't really help.
