got my hair fucked up right before photos

bro i'm literally crying in a chilies bathroom rn. my hair is already falling out and she didn't even curl it evenly. i have a mini straightener but i don't know how to do that stuff. i have an hour to fix my hair. what do i do??? i'm literally so upset rn. $50 to get my hair straightened and curled, but it isn't even lasting 10 minutes? she asked if i liked it twice and i had to tell her both times i need more curl. im about to risk burning myself just to do this because it looks TERRIBLE.
