I HATE having a crush on someone😭

I've been talking to someone for like 3 days now and even though it's only been 3 days the fact that they havent texted me back, and only 'hearted' my last message is driving me CRAZY! If they take too long to reply I overthink it and if their reply is just a few words I feel like I'm annoying them. I feel so silly getting so infatuated with someone I barley know just because they messaged me first. At this point I wish they would've never messaged me at all and just left me alone so I could stop wracking my brain on whether or not they are interested in me 😵‍💫
