panic attacks / seizures

Hello, I am hoping someone can advise me. My 18 year old daughter has suddenly begun having anxiety and panic attacks. We are not sure what has started them and have been to our local gp who has prescribed paroxetine and refeered her to a pschotherapist who has not yet been in touch! We have visited a hypnotherapist who gave useful relaxation info but was not able to put her "under" as she was too anxious. She is getting very upset/annoyed with herself as she has always been outgoing and sociable and it is affecting her social life. Her boyfriend is being very supportive as is college, she is in her final yr of a 2 yr sports course and cannot get into college. Each time she does try and go in she has what looks like an epileptic fit to me. Her arma and legs thrust out uncontrollably and she is unable to talk. It takes approx 10 mins for this to stop and I am really worried that she is doing damage to herself. She keeps trying to get in to college as she has been told to desensitise herself. This method seems to be working to a point with cafes, shops etc and after 2 months she can now go back in these places but at college she keeps having these "fit" type episodes. The doctor does not seem concerned about them but has not seen her have one. I am terrified but try not to show it around my daughter. She seems exhausted and barely conscious after them but keeps putting herself through them as she id determined to get back to her old self. Can anyone help/advise me please??
