Try not to feel guilty when your parents give you stuff. I used to complain when my mom sent me money or bought me anything more than dinner. She told me that she didn't begrudge me any of it, and that it was a way for her to feel relevant in my life when I was becoming independant more quickly than she could handle. I told her I really appreciated how much she cared, but made her promise not to spend money on me very often.
PS - this reminded me too much of Tynan not to post: http://indexed.blogspot.com/2007/11/jane-miller-from-high-school-was-tough.html
