You cant say "I know she is bipolar and has mental issues" and "its not an excuse to be nasty"
People with mental issues cant help themselves and sometimes cant realise. With friands with mental problems/bipolarity, the only way for them to be... "normal" was to take medication. When they had crisis, I just had to accept it and take the pain on me... because they were in pain too

I understand taht she has mental health issues, but this is still doesn't means she slaps him? And on top Peter was a patient with a heart problem. That is also a big issue. So her mental health problems don't really justify her actions towards her friend. I mean I understand her actions, but it was going to affect her more no one else. And Peter and his family is also in fault considering they saw all of those abuse and still didn't lend her a helping hand.
She’s such a shitty person , like I know she’s suffering because of her mother and has her own mental issues and stuff but that doesn’t give an excuse to be a nasty person that too to the “only” friend she has . And this guy Peter is so boring , no personality very plain . Like where’s the flavor ?
