I'm a huge procrastinator.
I know I always feel better when I actually take care of something - but in the moment it is easier to just put it off. I find I like being up against the wire, it causes anxiety/excitement and that is a familiar feeling. I feel alive when I'm in the struggle. Not a good adult life skill but it isn't uncommon.
I know this doesn't help. I do understand or relate to where you are, though.
