What is this and how can I get rid of it?

[Pozitron]

So around this period people decide where to go at college.
Some years ago, one summer I went on a camp and met a girl and we got a little close but I didn't made a move and the wind of opportunity closed. Then I got home and she went on another camp with other people. I regreted a looot and was really sad for a while. Then she got a boyfriend--blow.
There's this girl from my class.. which I wanted to try something last summer but I got the feeling that she is avoiding me and tries to stop me or make it harder.. whatever.
Now this is what's bothering me: I get some kind of feeling , maybe like jealousy when for exemple I know this girl will go to a different college than me or when I think some guy will have her. I hadn't been with her and I get the feeling that if I say something now it will be friendzone cause we've been all these years friends and we know eachother and it would be just not natural.. like you've been pretending to be a grephfruit and now all of a sudden you're an orange.

So yeah.. what's this s***? How can I escape it. I know I can't lose something I never had but still.. thinking other guy or actually other guy gettign together with a girl I like or knowing she will be somewhere else with somebody else makes me kind of jealous.. or something.
I think you know what I'm talking about.
This makes me be so afc and thing I would just go and tell her I like it eventhough I will get friendzoned just not to regret it..
I don't know what to do guys.. Excuse my writing.

Neediness.
I'd actually say your best shot that you can start applying immediately is to do the bootcamp, start a workout routine and eat a TON.

Yeah. I'm having neediness too. It will just make things worse in the end. I'm doing the bootcamp to change things around. Im tired of this, and you also should be!

College is going to be it's own thing. Don't try to bring your high school girls into your college life. Be ready to start all over with tons of new people at college.

Give it a name and it exists.
Don't give it enough attention for it to have a name.
Just ignore it.
