Can we still be friends?

So, here’s the story:
last week, I told my best friend that I have some feelings for her, and that we could be more than friends. she said that she feels the same way, but after that we stopped texting (we used to send more than 150 messages a day, and now we send like 10, only to say ‘hi’ and things like that)
today she came to my house and we started talking about us, and then we were just making out. I’m not sure why we started, but anyway. I was the one to stop it, I felt totally freaked out because she’s my b.f.f.e.
I think that nothing’s gonna be the same from now on. we can’t even talk to each other like we did about a week ago.
I don’t have any regrets, but I just don’t want to be with her. but I didn’t know that before. so, I started it, I ended it, and now I seem to be so stupid for doing so.
she said that we can still be friends, but I only want to disappear.

and the question is: can we still be friends, or is it gonna feel uncomfortable forever? and how would you react in a situation like this?
