Question for everyone about coworker.?

Ok Folks, a little background. I am a semi professional hypnotist and at times I get called on to do some hypnosis for parties and just for fun. Anyway...the other day I was giving a Christmas party for some coworkers at my school (about 20 in all) and I was asked to do a little hypnotism for them.I asked for volunteers and I hypnotized about 5 of them and had them do some really cool stuff (freezing hands, feeling hot, forgetting thier name) and one of the folks I hpnotized was this girl who I work with that I have had a crush on for awhile. We are just friends but she went under really deeply and was a great subject. One of the routines I did was I had her (and others on stage) have an from a handshake. She was one of the best. After the show she was really out of it and didn't remember anything but was upset when the was mentioned. I feel really badly. The question is, should I feel guilty and what should I do?
