Hang in ther Miss A. If you are having these troubles living at home still, you aren't ready for the world outside yet.. Hopefully she loves you enough to not kick you out before you can learn enough to be safe on your own.

That's too bad that she has stuff in your room. Sounds like a misunderstanding to me about when and how to get at it, though. Can you two sit and discuss this one item? Agree for when it's ok, and when it's not and how you'd like her to treat your room area?
