my bipolar mother

What should I do to help my friend with a bipolar mother?
My friend's mom is bipolar and she (my friend) was having to come and hang out a lot me and my cousin. What should I do? It is affecting my friend, obviously, but I do not know how to help.
if she / her mom is saying things that makes you feel bad then I say they are still wanted. my mother … no matter the best wishes.
