How can I stop this breakup?

I really fell for this guy, and I thought he was falling for me too. But last night he told me that he felt totally different about us, and that he liked me but pretty much doesn’t see a future in us. I can’t even sleep because it is bothering me so bad, I wake up over and over, and I can’t go to sleep at night, and I wake up early in the morning. I just got over a breakup not too long ago, and I don’t want to go through this again, especially since I want to be with this guy.. What do I do?
