How do I know be clingy in an unhealthy way?

Something I’ve realized is I’m clingy but I get really bad when I think I’m losing the girls I like I got to extreme lengths to keep that connect and more often then not it ends ip pushing the person I want to keep around away instead. I hate to say it but it can come off borderline obsessive I don’t like this about me and I’ve pushed away to many girls cause of it. If it doesn’t get me blocked it usually ends up getting me left on mute and that can really be heart breaking when the intentions are in the right place but the execution just leaves you looking really bad. This is something I’ve struggled with since highschool but recently the last year or so it’s gotten really bad. How do I stop this behavior any advice I know that it comes from probably two aspects of my personality lack of patience and stubbornness, If that means anything.
