I need to write this out because I've been in serious denial about it for months now. Thank you to anyone who takes a bit of time to read my words and share their experience.
I contemplated killing myself last night, so I'm at the point where I need to face the facts and change my situation.

I moved out when I was 15, I'm 25 now. When deciding to move onto the same property as my mom last year I really brushed off a lot of my memories and feelings from my childhood as related to being an angsty teenager. All moms are hard, all teens hate their parents, etc. We had a good relationship when I got done with school and lived in the same city.

Over the last year it's become very clear to me that she hasn't been able to handle the move and is very mentally ill. Her apartment smells strange and is extremely cluttered, she has trouble sleeping and has extremely angry outbursts throughout the day and then several times a day where she cries and whines. She won't accept help because people don't do things the right way- they don't sweep, mop or wash dishes correctly, they don't use the right ingredients if they cook, they put stuff in the wrong places, etc. 

She was on antidepressants (an SSRI) for a couple months and things were better, but for some reason she's not taking them anymore and the last few days have been unbearable. I've started hearing her calling my name in the distance and jumping at the sound of it in fear, only to realize she's not even at home. I'm also getting a lot of flashbacks from when I was a kid and she was physically abusive, which I had mostly forgot about or was in denial about. 

I feel guilty but I don't feel any sense of love for her. She wasn't a horrible mother and she did her best, she came from a tough situation too. Maybe somewhere I feel love, but not now actively. I feel overwhelming stress and crippling embarrassment for moving in here and taking out a mortgage, when my dad's side of the family told me they thought it was a bad idea. I don't know how to get out of this situation or how to tell people what's going on without embarrassing her, because there's still so much stigma around mental health issues. It's also really hard to think about what she'll and where she'll go if I leave but idk what else to do. 

She's not threatening her life now, or me, so I don't think I can get any authorities involved and she won't visit the dr.
