I wouldn't worry too much. Rylee acted like that after a few baths in the beginning also. I did the exact same thing as you..............I wrapped her up in a towel and sat on the couch with her trying to calm her. She trembled for quite a long time and even hide in her bed. She still doesn't like baths and I don't like leaving her with a groomer so I have a mobile groomer.............at least that way, she knows I am close by. Now she just goes "crazy" after her baths. Runs everywhere rubbing herself on the couch, the carpet or anything else she runs into...........almost literally!!!!
