What do I do?

I've been having a hard time lately trying to find a good middle ground between telling people that I think what they're doing is wrong by christian standards, and coming off as judging them. I'm not really sure how to handle it yet. Any ideas?

And so this is christmas

Well, Its crazy how much you appreciate your school when you have to come home for so long.

I don't like it here anymore. I mean, friends are great, and I've even gotten closer to a few friends here these past weeks, but I really want to go back.

My father doesn't really talk to me anymore. Maybe its because I'm different than the rest. My brothers are both very sporty, my older brother isn't really into the whole Christian thing, but since he is engaged and living with his girlfriend, my dad likes him a lot right now. My younger brother gets a lot of attention now that I am out of the house. But, I think its because I'm not afraid to express my opinions and views even if he doesn't share it.

Like when I was coming home from school, I had asked to not have the whole family come get me because I had a lot of stuff, but they did anyways, and he thought it was inconsiderate of me. The same day we stopped at Big Boy (yum?) and my dad got angry because I had a different view on tipping waiters than he. (I'm slightly nicer than he is). I feel alone here. I don't like all of the rules, all of the expectations, I just want to be myself.

Its Christmas, and my father doesn't even seem to mind if I'm there or not, but it has been a good one.
I'm not worried though. I know God is in control, and keeping watch on this whole thing, that is why I'm not freaking out, but if you could pray that would be lovely.

We've never been close, but its never been like this.
