so i have this thing where i obsess over someone/something for a few weeks or less and then i completely drop it

for example as a kid i would obsess over like ballet and then my thoughts 24/7 were about ballet i devoted all my time to trying to be a ballerina and sometimes it would go on to my mom signing me up for ballet but the second i thought i wasn’t good enough i would immediately drop it without another thought. 

and recently i’ve had this very sudden and very intense crush. i never saw her in this way before and when i found out she liked me i immediately became obsessed with her and it’s become a problem and just like every other time i think about her every second of every day and sometimes when it doesn’t feel right between us i get super depressed, i stay in my room and don’t want to talk to anyone. it’s scary to me how much a person can affect me like this. i also, don’t want to just drop her bcs we are rlly close friends and i would hate myself if i hurt her. 

does this happen to anyone else i honestly want to feel less alone w this bcs i feel absolutely insane rn
