I can't do it anymore.

Anything.
Everything is such a big deal for my family. I would like to get a book for AP Calc to study for the AP Exam on Wednesday, but it's such a big deal and nobody will take me to get one.
"Ask Crystal to take you."
"No," I said, very sternly.
I'm just tired of my "family" not being able to do things for me. Why should my friends have to pick up the slack that my family leaves? I'm just so sad. So fucking sad.
And nobody seems to care. I just want one person, one person who cares for me no matter what. Somebody that I know will never be disappointed in me, even if I fuck up, because they see that everybody makes mistakes. I think that I'm that caring, and I do that for others, why can't they do it for me?
I'm just sad. I'm confused. I'm tired. I'm sick. I'm crazy.
Yes, I do like somebody. No, I won't tell them. It'll get ruined, feelings won't be reciprocated, and I'm just not doing that anymore. I just need help.
