Is it normal to have weird feelings a crush, physically away from her?

A few days ago, I told a girl about my feelings because I just wanted to let it out and move on. Being nervous and shaken about the whole thing it is as if I was fighting with my little demons in my mind that make my constant thoughts about her. I just wanted to let it out and I'm grateful to know that it came out at the right place and at the right time - not to mention that it was raining that day as if it was some coincidental sign from the universe (not that I would believe though). I know that I took the risk, I'm ready for those consequence that is been given out whatever it may be.

Since its been a few days of not seeing her, I want to keep my distance away from her so that I can cool myself down emotionally not to cause anymore drama giving her burden of seeing my face (she didn't tell me about her thoughts though right after I told her, but it became awkward) giving me time to recuperate so I can move on.

I was on Facebook seeing her profile as I tend to have those weird feelings about her again, even if I am physically away from her (I even deactivated FB because of her among other reasons). I couldn't even look directly in her eyes of the picture, as if I need to shy away from her. I'm worried if it ever happens with that same feeling when I'm on her presence physically, even telling myself to be brave with the current against her - pretending nothing has happened, life goes on as usual.

If you were me, what would you do?
