How unattractive is overthinking?

[Anonymous]

There's this girl i've been seeing for a couple months, and i like her a LOT. We're in the phase where making out is normalized if that gives you guys some context, but since i'm naturally a very clingy person and i'm always concerned with how people i know are holding up I tend to overthink every little interaction and it's pushing her away. sometimes i'll send an apology for something I did or genuinely ask if she's doing okay because she gives some indication that she's depressed or feeling down and i'll just get a response an hour later with her laughing at me or her friend telling me to shut up. i know i'm clowning really hard right now but every time something happens i can't help overthinking it and honestly i can tell she's liking me less because of it. Should i just let her drift away and find someone who will make her happier or should i just keep trying? Back to the main question though, girls, is this type of overthinking and my tendency to over-care for people a major turn-off or just a minor annoyance? and for guys, have you had challenges as an overthinker that you were able to overcome, and if so, how? I would genuinely like to change, i just don't know how. sorry for the long post, but i look forward to your responses :)

Clingyness can be unattractive. I can't tell if she's really into you or not. The way you can cling less is by being busy. Fill your time with activities. It'll make you a better person anyway.
