Enough

I can see what your sister might be doing, and why. Part of it might be paranoia. In her mind she is protecting your dad, and might not see what she is really doing. She is trying to play hero, which is another sign of mania, and wanting to save everyone. The other thing about her attacking evryone that comes in to her life is suspicion, and paranoia. Somethings that bipolars do are very contradictory, and don't make sense at all...LOL

We tend to push everyone away. It's a form of insecurity. If shae doesn't feel worthy of real relationships she may sabatage them before, they can get close. I agree with red on the gifts. She might be trying to overcompensate for her behavior.

I have been known to be a people pleaser. I tend to want to play the hero, and try to save people. I also do it to get approval. I have played the martyr. Blaming them when they don't do what, I want them to do.
