I had this problem. It crippled me. One or more of the following solved it:

- just time plus regression to the mean

- talking with a therapist, for a while

- being hit with a completely different enormous life stress, allowing me to say "fuck it" to all other anxieties

While it was ongoing, my coping mechanisms were:

- ditch social interaction in favor of putting myself near the problem for hours at a time with nothing else to do until I made reluctant incremental progress

I do not recommend that coping mechanism for anything except that which you need to literally survive.

When it was very bad, the following was not helpful:

- breaking into small chunks; fear-avoidance can be about starting, but in my case it was literally about producing any results visible to anyone else
