Sorry you're having a bad time.

Do you have somewhere safe to go? If you don't then I doubt it will help either of you to disappear? Being angry with someone because of resentment, annoyance, inconvenience etc doesn't mean they want you to disappear from their life. Your mother will probably be devastated if you just disappear? *

*Not to seem harsh with this comment you know but as a mother and as someone who constantly wants to disappear (which I used to do) I think it's important to be rational, regardless of the emotions involved.
