For situations like these I'm with Perna. This sounds almost like an OCD type thing and I do think anti-anxiety meds would be a good first step to symptom control.

Sometimes, just interrupting the anxiety cycle quickly can be of significant benefit. You may have even forgotten what it feels like NOT to be anxious. Good lord, are you exhausted?

So... I would likely seek out the help of psychiatrist first with concomitant talk therapy. Anxiety/OCD can be a very complicated issue. I do think, in the long run, it can be managed with talk therapy. There is an immediate issue of relief. There a good options out there for it.
