Why do I leave procrastinate and avoid things to such extremes for no reason?

So I’m a big procastinator but that’s not new. But I take it to a crazy extreme. The latest example is a paper that I had ample time to work on and avoided starting until the night-of and I’m still procrastinating. I just read the requirements and it’s only a 3-page paper – something I could’ve done easily in a day or 2.

Projects I take on for work, I don’t start even though I have all the resources I need in place. One project is literally years overdue.

It seems like I spend all my time actively avoiding what I should be doing and then retroactively driving myself insane to cope with the overdue work.

I don’t consider myself a stupid person, the tasks at hand are achieveable, I just don’t seem to be able to drive myself to do them. Anyone else have this problem? How did you ‘fix’ yourself?
