I spent about a third of 2021 more or less consumed by this phenomenon. In my case it was triggered by job searching: I quit my existing position, intending to do a leisurely search over a few months... and then avoided nearly everything related to the job search for over four months. (While still experiencing a ton of stress as a result of constant anxiety and guilt about it.) Once I actually started, I landed an amazing new position within two months.
The thing that made the difference for me was directly and consistently involving my girlfriend. All she did most of the time was sit in the same room as me, working on her own stuff, but some combination of being unable to completely avoid working while she was there, having her there to vent anxiety to, and being able to make commitments to her rather than myself made an enormous amount of difference.
I'm not thrilled with myself for the procrastination I did in the first place, but I'm taking it as a hard-won lesson: doing difficult things can be vastly easier if you have someone you trust as support and confidant.
