Hmmm. Of course, I am only hearing your side of the story.

Objectively, I would think your diagnoses would make you a bit more difficult to deal with, but on the other hand, I can understand why you would want to be more independent.
Since you are out on your own, then I would think you ought to have say-so on what you do on a computer. What kind of gaming were you into? Could it be considered dangerous or wrong, somehow? I think they can get rather addictive.
My mom tried to overcontrol me, so I can understand how you feel. I got very angry and then depressed. So, I can definitely say she was not healthy for me to be around a lot---even now, many years later, when I am a married woman with grown children myself.
Do you see a counselor or therapist? If so, then what does he/she say?
