Head over Heels?

Ok I seem to be in a state of infatuation, totaly and completley and i cant be certain if its reciprocated. There is some chemistry between us I think but then again it might just be me misconstruing things beacuse I'm falling hard lol. Heres the go shes in the same cles as me, we do the same degree and work in a simmilar research area. She makes it a point to talk to me, she looks me in the eye, she sits next to me if she can, she gives out this incredibly radiant smile whenever we glance at ecah other, she makes it a point to say goodbye to me and shes amazing while the whole time I sound like a fumbling idiot lol. So what to do hey?
