Girls, Why is conversation feeling a bit awkward between me and a girl?

I really like this girl. Tonight the moment I saw I got this really sick feeling like my stomach turned upside down. I lost my appetite and everything.

She and I have spoken before but I certainly felt something happen. Lately when the two of us have been chatting it has felt slightly awkward for no reason.
