Life is passing me by...

Good afternoon. I'm 30 years old, and my entire life I've lived with toxic parents who are irresponsible and unable to adapt to adult or serious life. Due to depression, OCD, and diabetes, I grew up physically and emotionally weak. The family has always been filled with endless arguments, fights, and profanity. My older brother also has a mild autism spectrum disorder. He's interested in esotericism, astrology, and other pseudosciences. He's withdrawn, doesn't like people because of traumatic school and youth experiences, and unfortunately, children unconsciously bully and tear apart people like him. After the full-scale war started, he quit his job and moved back in with us. He got my mom hooked on horoscopes and tarot card readings. They talk for hours into the night about complete nonsense. My mom is a tyrant and manipulator—everyone in the family has to do what she considers necessary and correct from her point of view. Since I was 22, I've tried to move out and start an independent life. Unfortunately, I keep falling for lines like, "Just stay one more year and help out" (my parents have been doing endless renovations for years that never get finished). They often manipulate me by playing on my health concerns, especially my mom’s heart issues. I could say a lot more, but there aren’t enough letters. My current problem is that I’m planning to move and fully separate. The only thing holding me back is the emotional nightmare from my mom and her poor health. On top of that, she was diagnosed with breast cancer but refuses treatment, and she also has a severe mental state—constant fears and worries about everything. I feel like I’m sitting on a powder keg that could explode with any decision I make.
