One Sided Liking

So I've been talking to this guy who lives in another state from me, since roughly 8 months. I've liked him for some time (also have been wanting to tell him for so long) and last weekend I let him know over the phone while I was drunk. It was the first time I've spoken to him over the phone, and so far the last time aswell. Anyway, since I poured my heart out to him, I've felt really shitty. I thought telling him would be great and all, but every time I think about letting him know how I felt towards him, it makes me teary. I feel like I effed up our friendship even though he tells me nothing has changed. And I know for a fact that he doesn't want a long distance relationship and neither has he told me if he likes me or not. 
So why do I feel so shit?!
