Providing a roof and food, etc. does not a good parent make. I don't mean to insult your father, I'm just trying to say that you don't have to feel guilty for having problems with him just because he provides for you materially. A lot of people think that they should worship their parents and do every ding dong thing their parents demand of them just because of this, and while it is nice, and it is part of being a good parent, it's not even half of what it takes to be a good parent.
*hugs* Hang in there.
