I feel so stupid

All of a sudden I am having anxiety and panic attacks. They scare the you know what out of me. I don't know if they are from a new meds(Nabumetone,methocarbarmol,trazodone )I called my Dr. but she did not call me back today. I also get all shakey inside. ANY ideas?? This is really upsetting, I'm not normally like this and it just started since I started these meds. Do any of you use these meds and had this problem??
I'm bouncing off the walls and scared to death.
