I think it's just loneliness and whatnot. If a girl shows me just a little bit of attention, even when it's usually just friendly and nothing, then I'll think about her a lot, even though I'm not even on her radar. And inevitably, they will stop paying attention to me (because they never really were in the first place, they were just being normal), and then I'll like them only because of that and fall harder for them, even if they aren't good for me or if I don't even like them to begin with.
There's even a girl who showed me more attention than any girl did two years ago, and two years later after we've both moved on and made different friends and don't even talk, I still cling to that.
Maybe I'm just not meeting enough girls, but I'm not a bar/club guy (tried it), and school is consuming all my time so I'm stuck with these girls every day.

You have low self esteem and self confidence. You need to work on these things and grow to love the company of your self. Its when we come to be happy by our self (being single) that we can have an enriching relationship with others. So work on that before you attempt to get into a relationship or even pursue something with a woman. You have to work on these things now because if not they will be toxic for whatever relationship you do get into in the future. They will ultimately cause the end of the relationship and cause you to become even more needy/clingy once it happens.
So work on loving your self and appreciating the time you have to your self before you pursue a relationship with a woman. I hope this helps! :)2
