Congratulations Knowsnothing ( sounds like a misnomer ).
I fear that the most difficult thing for you will be your mums emotional blackmail, if indeed she trys that.
It is not a nice thing to do, but understanding that she is scared for you, and for her, might help you to pardon it.
In the meantime, enjoy your new freedom.
In a past post, you spoke of a good friend who you can confide in. Are you in touch with him at the moment?
