My mom raised me and my older brother as a poor single mom. I now think is a narcissistic bitch. I KNOW for a fact that she will never admit any of mistakes she made when raising me (she treated me like shit, constantly beating me, calling me useless, degrading me, making me hate other people, etc., even though I had to take care of myself since I was 6, working at night during summers to "help" her buy my own supplies for school, traveling ALONE on public transport, ...). I also think that she thought I was her ticket out of poverty.

Even to this day I suffer the consequences because I made the mistake of believing her victimization and think I could help her, even though I realizes some years ago that it all was self-inflicted bullshit to draw attention to herself. But I'm stubborn and can't help but hope that one day she will stop being retarded and will let me help her have a better life, and will also tell me she's grateful for the times I've helped her. For example: I helped her buy the house we live in. I paid more than half of the price on the condition that half of it would be mine, and when she realized it wasn't a gift for her to take advantage of (she wanted to rent some rooms) but a way for me to also have my own place (which apparently wasn't obvious enough), she tried to scam me with some money I had lent her.

How do I stop giving a shit about this dumb, narcissistic, entitled bitch? Should I just leave the house and wait for her death to come back and finally be able to build a normal life and have my own place?
