What Causes Recurring Pressure In Head Followed By Panic Attacks?

I have had pressure in my skull off and on for the last 3 years accompanied by depersonalization, fear, and panic attacks. im wondering because i have gone to the Emergency room so many times ive racked up a bill that you wouldnt believe. So im wondering if going to a head doctor would be best, im going to see a family doctor soon and i have a psychologist im seeing, so am i on the right track? Symptomps are as follows from varying levels, Pressure in all parts of the skull, depersonalization or derealization, lack of breath, tight chest, hot n cold flashes, racing mind, body shakes, mind will not slow down, feeling of altered depth perception . and general weakness after i have a panic attack weakness and pain in neck sore or easily tired in neck... loss of memory and insomnia. i hope you can provide something for me. thank you very much.
