My mother is going crazy, please help

She has always been (I don’t want to sound rude) crazy. She always thinks everyone is against her, very narcissistic, becoming very irrational, crazy thoughts like I never take her side but only my dads, she won’t listen to advice and thinks we’re putting her down or trying to insult her even the littlest piece of advice, anger issues, possible bipolar. 

With that being said, recently she’s been getting worse. She has 0 money in her savings as she’s a impulsive buyer and lives paycheck to paycheck. Now she wants to buy a new car. Right now we have a 2020 Toyota Corolla. She is freaky about it being in my dads name and not considered “her car” when my dad bought it for her. He’s only doing that to get better rates on the insurance but she thinks he’s doing it because he doesn’t trust her. And now she wants to move out, divorce my dad, and get an apartment with her friend

I tried to talk to her today about going to a counselor or a psychiatrist to talk out her issues as I can see a lot is bottled up. She got into her headspace of “your against me all the time” “your only doing this cause you don’t like me”, etc. She gave me a very abusive child hood mentally, physically and emotionally. She too was abused in her family in terrible ways. I don’t blame her but we’ve had our moments. She always brings it up and says “Yeah Zach you just wanna mentally torture me for the rest of my life cause I abused you”. I don’t bring it up at all but she still says it.

I love my mom so much but she’s loosing it lately really bad. I could say so much more but the list would drag. I’m setting up a psychiatrist appointment either way. I don’t know what to do anymore and I feel like these little moments are gonna turn into one big moment and turn into something bad. Any help? Thanks reddit
