I hit my head 4 months ago with little fanfare. However, 6 days later, I had a panic attack because I was worrying like crazy. It was only AFTER the panic attack, that my symptoms started. The symptoms took about a month to subside.

2 months ago, I smoked marijuana and had another panic attack. Back came the symptoms, which are present today.

I have no history of panic attacks and no history of major anxiety (although anxiety does run in the family). I've used marijuana rarely throughout my life, but never had such a reaction.
I've seen my DR and a neurologist. Neurologist suggested I might have GAD.

Could the hit to my head have "brought out" the anxiety in me?
Is this medical or psychological in nature? Or both?
Any advice on what to do next in terms of treatment?

Part of me wants to wait it out, part of me wants to seek help. I'm terrified my DR will refer me to a psych who will simply dispense SSRIs and send me on my way.
