Can you ever be near your mother?
No offense, but it sounds to me more like your mother has issues of some kind.
People change, and I'm sorry your friend changed for the worse. And it's easy to feel a good or bad vibe from people, but if you can not even be able to be near your mother... wow. Honestly, your mother might have a little bit of a disorder.
Edit: Again, I don't mean any offense, but...
