I am pretty sure my sister in law is bi-polar. She is like my best friend but some parts of me wants to run away from her. First of all when I see her calling I brace myself when I pick up to see if she is in a good mood or not. When she is in a good mood we could have great laughs, great conversations, she will buy me lunch, offer me rides, everything. When she is in a bad mood.. NOTHING is clear from her wrath. She will say the meanest things I have ever heard some one say, she will flip out on her boyfriend, throw his phone, say things that will purposely make some one feel so stupid, and then most likely apologize later. She has gotten into physical altercations because of her temper. She is depressed sometimes. She tells me that when she gets angry her heart beats so fast and sometimes she gets dizzy. I dont know what to do here are my main concerns:
1. Is she in fact bi-polar?
2. How do I stay close with her and explain to her my concerns without her flipping out on me? I have tried and she gets super mad then we never address it again like nothing ever happened. (One time she flipped out on me for taking the bus home when we were at school together cuz I had somewhere to go! )
