Early Film Shoot

at around 2am this morn­ing i woke up a lit­tle bit anx­ious. ok, alot anx­ious. my film shoot was to begin at 4:30 but the anx­i­ety came first. i lay in bed while my mind raced and wor­ried for an hour and then some. i dozed. at 3:45 i got up went to the bath­room and heaved a lit­tle bit. some bile and most of the anx­i­ety left with it. i do that when­ev­er i get super­stressed. i took my show­er. i went to our loca­tion and began set­ting up. the tal­ent arrived around 6:00 and around 7 my mind went soft-focus. we fin­ished the shoot at 8:45 and i drove one of the tal­ent back to his dorm. i have just come back from my 9:30 class. it is 11 and i don’t know what the hell is hap­pen­ing and i don’t care i’m so tired. not just tired, not just fatigued…i’m non-func­tion­ing, but that’s not right either. is there a word for what i am feel­ing?
