It happens, I'm 18months clean.

The fact you were excited tells me perhaps you're not socially anxious? (I am severely and would've immediately gotten nervous for someone being seated by me.) If you're not, that's a great step up in being able to make friends! Try building yourself up to making friends by chatting with people you see everyday. Like the server at your coffee shop, or your mailman, whoever. You have no idea who could be an awesome person until you try! If you're into reading, you could try talking to people with books you like at a library, or if you like music, same but at a music store. If worst comes to worst, I've found online friends are wonderful. The idea they're not "real" friends comes from people who don't have them! Good luck OP, I know how hard loneliness is and it isn't a fun place to be.

I'm your friend:)

I know how you feel!

aw how sad ill be your friend if you whant.

I'll be your friend :D
