Hi, Beth! Usually, we go to a regular doctor first and rule out anything physical that could be going on. Some illnesses can cause panic attacks...like thyroid conditions. So, usually, bloodwork is run to rule these things out. Then, if it comes back good (which it usually does), make an appointment to see a psychiatrist if you want medication and also a pyschologist or counselor for the counseling end of it (which is very important).
I hope this helps you! :)
