I too resist when I know I should be doing something. It's especially bad if I make plans with someone. I will fret and worry all week and almost always come up with an excuse why I can't go at the last minute. This also has gotten me in trouble financially, putting off paying the bills, ordering out when I should really have gone grocery shopping, making doctor appts. etc. This may sound weird, but I've forced myself to schedule an "icky" day - where I have to deal with things that I don't want to like going to the store and paying the bills, calling customer service when I have questions, etc. I hate "icky" day, but I find when everything's taken care of it didn't really take me all that long to do and then I reward myself for even the smallest achievement. Small reasonable goals, before they become monsters.
