I’m Too Clingy For My Own Good…

So, lately I (19M) have been reflecting on myself, my last relationship and overall mt dating life and realised I’m way too clingy for my own and others up to the point where it’s destroying my chances with girls (even when they’re the ones who first interested in me). I would constantly text them every day, expecting a reply straight away, and when I didn’t, I would get anxious about whether I had done something wrong to make them mad or if they had lost interest in me up to the point I would ask them for affirmation. Another recent thing I did (which was a big mistake) was to pretend like something bad had happened even though everything was completely fine, just to get their attention. I have realised that this is a big RED FLAG as it could be perceived as annoying or overwhelming, which I have to work on so I won’t keep self-sabotaging myself in the future when it comes to relationships.

What can I do to stop being too clingy so that I can stop self-sabotaging myself in the future?
