is this anxiety or smth else?

i used to think me panicking over stuff was just me overreacting but right now it seems like there’s a bigger picture to it.

it got worse the beginning of this year when i convinced myself i could be pregnant, which is honestly really fucking dumb bc i didn’t have sex but i was involved in some sexual acts (but there’s no possibility whatsoever), but for some reason i can’t get that thought out of my head?

it’s getting so much more worse and i honestly don’t know what to do. i can’t talk to my parents because i come from a really religious family where no touching or kissing is every allowed. i can’t talk to my friends or my boyfriend because they think i’ve gotten over it already. i don’t want them to think i’m crazy. i don’t want to humiliate myself either.

please help.
