Friend A, who has been mistreated, is nice to me but a bit toxic sometimes, and everyone says so too. I never stand up for myself because they already have been through a lot., but everyone says she is toxic and bossy to everyone and I shouldn't be friends with her, although we are really close. Friend B, the one who mistreated Friend A, is really nice to everyone and is very shy but extroverted with friends. She can sometimes ask for too much that is not hers (she always asks for my snacks in my lunch..), but overall she is a good friend. But recently it was confirmed that Friend B had said something bad about Friend A, leaving me to pick a side. Friend A has been trying to manipulate but at the same time gently get everyone on her side, because she says she is the victim and Friend B has made everyone seem like Friend B is the victim and Friend A is the bad guy, which Friend A says is not true. Friend A is acting very grumpy to me these days, and makes me feel bad if I tell her that ganging up on Friend B is a bit dramatic. Both A and B lie a lot, and sometimes I don't know who to trust. What should I do?! Please help!
