Just told I have 30 days to leave, for no logical reason

For context, I’m a 19yo guy still at home, and my mom is bi-polar and addicted to weed and shrooms, and just sits at home all day.

For all my life I’ve dealt with her blaming me for almost everything negative about her life, and it doesn’t help that she’s chronically ill on top of it.

Since turning 18 she says that I never contributed to the household or try to put my life together, even though I work full time, pay them $1100 a month for a mixture of a car payment, insurance, and rent/my share of utilities, on top of taking care of her when she gets sick and doing a couple hours of chores a day.

While this goes on my dad, who is the only parent working and doing most of the household work, just follows along with anything she says while refusing to listen to my side of the story.

This has been going on for at least the past 6-8years, but it got to the point where I’m blamed for any issues whatsoever, including the septic system backing up and flooding the only downstairs toilet (there are 3 in total), and for my brothers “poor performance in school”, when he’s actually doing really well.

I’m just tired of being the family scapegoat, and I know that they are going to beg me to come home after I leave. Has anyone else experienced something similar? Any advice? And what could I try to do better? Feel free to ask for more info. It’s hard to get everything down in a single post, and I left a good bit out.
