These ideas may sound stupid, but sometimes similar ones work for me- if only temporarily.

I lose focus easily, and can get distracted and carried away with my funks. It is hard to make yourself do things that you know will help.

Maybe you might want to start a list of things, positive or distracting activities- that you can refer to when you are stuck, since when you are in the middle of it it is harder to think clearly. And then just pick one to do- like walk 5 minutes, do deep breathing, do a word puzzle, make a phone call, anything to just change the pace of what you are doing. Who knows, you may even want to continue it!

Once, I set a timer, and every time it went off I forced myself to get up and walk for 5 minutes. Knowing there was an end to it made it easier to start! And at the end of the day, I felt better that I didn't just do nothing. In fact, as I was using up my 5 minutes, I picked up a long the way, and that made me feel better to.

Yes, this is a kind of game playing with yourself, but i think that even simple steps can create movement and change and that is good.
