So I'm in highschool, and whenever I come home to my family, I can't be happy at all. We've never had a great relationship, but now I'm finding it meaningless to even talk loud enough to hear. Whenever my Mom talks to me, she talks as if I'm in grade school, in the simplest terms. It seems hopeless, as whatever I say doesn't matter, even though both of my sisters are always cared about.
I can't help feeling like I'm the odd one out. (I'm adopted already, so there's another card to that pile) and whenever company visits, I usually hide in my room or don't talk at all.
I can't talk to them about it, certainly because there are some things that I'd never want to tell them, and I've always envied people that can talk to their parents about normal things. I don't agree with my parents opinion of a lot of things, and they seem to mock a lot of things that I feel strongly about.

Is this relationship really worth it? I can't help but think about the future when I'm visiting for Christmas, and I'm horrified that I'll feel like this.
