I can understand the PTSD part. I was diagnosed with it because of the sexual abuse I went through (having vivid nightmares and having triggers). My boyfriend family took me in at one point too because of how my mom was and my mental health was in shambles. Now that I'm more "stabilized" I moved back in with my mom. Her and I haven't even argued since I've been back. It's good that you're working towards a degree and living out on your own. So far I haven't made much an effort to do so.
