Having been a victim of anxiety in the past, I can say that YES, anxiety could be the problem!! If I were you I'd take the Ativan and see if it helps. But I would wait and take it at night when you're going to be home because you don't know how you're going to react. You can't be out on the street driving - you might react badly to it. Make sure someone is home with you too.
I had a very bad reaction to Ativan - I went into a complete Blackout when I took ONE Ativan. I was functioning, but I didn't know it cause I was blacked out. I was walking around, doing things but I didn't remember a thing 2 days later when I "came to." Yes, it was 2 days later when I finally "came out" of it. It was bizzare. I scared my family half to death!
So go ahead and take one and see what happens, but stay home.

Best of luck and God bless. Hugs, Lee
