i don't know what to do without him. please help me

I don't know what to do. My boyfriend moved abroad today and I feel like I'm going crazy already. I don't know how I'm going to cope without him. I feel like there's no one left here for me. My friends are trying to help but no one can except him. I know I'm overeacting but i just don't want to live without him. He's the one i can turn to with everything, and he's always there to make me feel better. His smile and hug just make things seem bareable. Now he's gone and I'm lost. Please has this happened to anyone else? How did you cope? did it get easier? I love him so much.
i posted this in the love and romance thing as well but i don't know if anyone will reply.

For the next 2 months he's stahing with family in different places. he said he'll write to me, but I don't know if I can reply. I can't email him cuz he's had to leave his computer for now. After these 2 months he's coming back for a couple of weeks, then going back and actually moving in. I'm trying to keep myself busy but it's hard cause sometimes when they're all laughing, it makes me feel worse and miss him more.

Him and his mum are moving to be with his family cause of a lot of problems they've had. roughly 785 miles. I went on some distance website. I know thats pathetic. We've been best friends for ages, and even though we knew we had feelings for each other, did let anything happen so we only officially got together a month ago. Thanks for trying to help me with this!

We're both only 16 which makes it hard. Harder to see each other, and hard to have a long distance relationship. I think we will have to end it and try to stay friends by keeping in contact. But I still don't know how to cope. I just can't believe this happened to me.
