Thanks guys for the support. I am doing my best to deal with this. I am at such a high level of stress overall right now financially and work-wise that piling my sister on top of this is more than a little overwhelming to me. Going to the beach with her wasn't so bad and she was not high at the time, so that was good. I did, however, work on setting some boundaries. I am withdrawing my support from her and it scares me to think of the consequences of this which include potential ridicule, anger, and abuse. But I don't know what else to do. She asked me if she could borrow my bicycle while she is in town and I told her no, that I need it and have been using it. I don't want to let her borrow my things anymore as she so often is careless and destructive. But telling her this was very difficult for me and my heart was racing while I told her no since I never know whether her reaction will be violent. There was anger but not violence. Then she asked if "things went down" with the guy she is living with whether I would pick her up in the middle of the night. In the past, she has abused me (with screaming, and violence) when I come to pick her up if I am the slightest bit late. So I told her that I would come if I heard my phone but I might be sleeping and couldn't promise anything. Again, anger but not violence. But I don't know what the future will hold. I am so very afraid of her and wish she wasn't in my life. In our meeting she acted very nice for most of it but I know the wizard behind the curtain and just being around her at all sets me on edge, puts me on high alert. It's so sad to me because she is my sister. I am full of guilt for setting these boundaries and fear future abuse from her in retaliation.
