stress.

I believe that the reason I'm having trouble losing weight is stress. 90% of this stress comes from my "father". Biologically, he is my parent, but emotionally we are at a permanent disconnect.

He is abusive, controlling, and judgmental. He smokes marijuana and drinks beer every day. I am not exaggerating. I moved out of his house in 2008 when he decided it was okay to take his anger out on me physically. I have not been back there yet.

Now, the only tie I have to him is my college fund. He has control of it until my birthday, which is September 8th. It's not that far away, but my financial deadline is next week. He does not trust me [with MY money?] and says I can't be trusted to pay for the things that I need.
Now, a question. Why would I spend my college fund on anything other than COLLEGE? I'm an average girl from a middle-class family, I have everything I need and most of the things I want.
I have been waiting YEARS to go to this college and I got accepted! I have almost a full scholarship. I would NEVER do anything stupid that would jeopardize my funding or my career.
The real problem here is not me and the level of trust. The real problem is that he wants control. Over me, and over my life. And I'm almost a legal adult, so he is losing that control, and it angers him.
I wish I could just go it alone and ignore him until I have the control over the fund, but I NEED that money for my textbooks and fees that I have to have by next week.
So what do I do? I don't have that many options. I guess I have to play nice until my birthday. Then I will be done with him for good, and I won't change my mind.
