>>12126144I moved in for a short period with my mom (dad dead) because nojob when I was 25. It literally drove me insane from her nagging.
Then she got a boyfriend, moved in with him (leaving me alone in her house) and I also got a job (that I still have now, 5 years later), and our relationship improved dramatically.
It's honestly eye opening when I think back on it, but stress factors really play into a relationship with your family. Hers was my dead dad, fear of being alone, etc, while mine was because I was a jobless engineer for a period of almost a year.
I think the hardest part is identifying these stress factors, and it's obviously easier with hindsight. You said it was your mom and gave a bunch of reasons, but there's probably also something wrong with you. You'll either find out or not, but that's life.
