What should I do?

I really like this guy...im going to be a junior in hs and hes about to b a sophomore in college. Were only 3 years aprt. Everytime we talk I like him more but I've only met him once thru my bro and we've been talkin since I was in 7th grade im going to be going to a concert with him and he knows that I like him. And right now im so nervous to even talk to him now that I realize that im going to be with him. Is there a way I can overcome this. I dont want to feel uncomfortable and then blow anything because ill end up feeling sick to my stomach because ill b so nervous

Don't worry at all! I had a problem just like this, the girl turned out to be the girl of my dreams and she is still my chosen mate, perfection must be felt before it can be held, he most likely feels the same way, has the butterflies and hopes to god he won't mess anything up when you actually talk in person and hangout, if it's right you will know by the end of that first 'date', you will do nothing but smile until you see him again, congratulations if this is what happens, it's the greatest feeling in the world when you find that one true love, you know it's true because it feels different from everything else you have EVER had.

You just need to relax and if you have known him for a while then talking to him should be no problem just be yourself and if he doesn't like who that is then he isn't the guy for you, but really all you need to do is relax and stay calm and remember just be yourself because most guys don't like girls that pretend to be someone they aren't. Hope I helped, and good luck with everything. Have fun at the concert! :D

chill, guuurl!
