Am i just overreacting and being a teenager?

Okay so this is going to seem pathetic but whatever. So i meet this guy online when I was in 6th grade and we talked here and there but nothing really serious. Then in 7th grade we talked a lot kinda. And the summer going into 8th grade he said some pretty i guess deep and nice stuff to me. Keep in mind we talk until the late hours of the night he is a year older then me. But i became really sad and upset because i knew i was going to miss him until we talked again. So then on my birthday in 8th grade we talked about a lot of things and i missed him so much. But at that point he had a girlfriend and really liked her. After that we didnt talk for almost year until this year in september of 9th grade and we promised we couldlnt go this long without talking and that we would talk again christmas break. He said snice we have been talking so long we should meet snice its been like 3 years. I just finished talking to him again last night but this time we acutally heard each others voices through skype and talked into the wee hours of the morning. I know im not going to talk to him again until august but i just miss him so much...And i dont know what do. I never thought i would like someone online! how can i let this go? do you think its worth meeting him in well i guess 2 years. Idk please help. I dont care if your mean or not.

And everytime we talk again i get shaky and nervous and light headed and sometimes make myself sick because i know when we are done talking i wont see him for months and i will be all upset. I honeslty just dont know what to do.
