im so sick and tired.

of being sick and tired. I know thats a song, but it fits how i feel almost perfectly.
I dont understand, how i wake up and go to school and act perfectly normal, and perfectly happy, and live up to the "popular" title i've been given. But once i go home i feel lk a no one. I always doubt myself, Im always tired. I never do what i say I will. and i just dissapoint basically everyone i know. I feel lk a fake. Although I know im not. My boyfriend broke up with me recently. There kind of was no reason for it. And now he wants me back. I really miss him. But sometimes this tired feeling just makes me feel lk not putting any effort into another relationship with him. I just dont know what to do. And my answer to everything lately has been: I dont know.
