Tired

Something's wrong with me. No shit! It seems that whenever I try to do anything I become tired easily. Even just trying to concentrate on the piano music sheet makes me tired. Just going to thai lessons makes me exhausted. I hate being exhausted. Is it the fuckin' medicine that's causing this. Will I be able to learn thai every day? I can never stay up late because the medicine makes me sleepy. Fucking Abilify!
