I'm afraid I have to say that in my experience talking therapy is even less effective than drugs, which at least do something. But again, I'm not discouraging anyone from pursuing these pathways: do it if you can, and as soon as possible, partly because the problem's unlikely to get better over time. But don't get your hopes up, if you're primarily an anxious procrastinator.

(I should add that IME "body doubling"/"task shadowing" is somewhat effective, though not very consistently. It's also probably the hardest intervention to get, though maybe things like Focusmate https://www.focusmate.com/ might help with that nowadays.)
