Thanks everyone! Bugs, I'm sorry that your sister won't let herself have a real relationship with you. From what I know of you, it's her loss. I hope that my brother and I never get like that; we're really close now.
For those of you with healthy siblings or a brother whose bp is under control, I can understand why you would be envious.
Merlin, you're right. I should discuss this with my therapist. It's really rooted in my hurt from dealing with 7 years of untreated bp.
