Thanks, Piglet. That book has been suggested to me as well as a few others but so far I have not gotten around to actually picking it up. I've found that while somewhat related, my issues with my sister and my drugs are pretty much separate. I was kind of working on some of the sister issues, just getting past stuff and accepting that she and I are not friendly and never will be, but I started doing drugs and quit caring. And then I had to work on staying off drugs (still do) so the sister stuff is on the back burner, on the top shelf, and in the back of the closet.
