They got into it again

My mom and sister got into another physical confrontation today .to recap they got into one a week or two ago over a remote and started to fight this was much worse it happened in a public building at the laundromat.my sister wanted to go to the car but my mom told her no to wait till we were all done in a few minutes so she started yanking at the keys on my moms neck and they started fighting me and my brother broke it up. she kept telling her to get away from her but my sister kept coming back so my mom swung once and missed ,finally my sister walked came back in asked for the keys my mom refused and told her to walk home so she did.i was so upset theres no reason for her to act like this shes leaving anyway in two months.my older sister says she might have a mental illness for her to behave in such a way. I just don't know how long i can hold in the scream if they keep fighting like this especially when one goes to jail for hurting the other or both

I know this must be very hard for you to watch. Has your sister always had this anger issue or is it only recently the the arguing has started. I don't guess that your sister would consider counseling for her anger issues. Hopefully, things will get better and not escalate into something that has the police intervening. But call 911 if it gets bad.

I'm not sure at all what you're asking here.

It's unfortunate that they fight. I feel for you and would be uncomfortable too but I'm just wondering, what is it you're asking here?
