Need Motivation to do my work !

I work for myself and periodically go through a period of time when I feel like I literally can’t force myself to physically sit down at my desk and start working. Days go by and I do a hundred other things but can’t get myself to sit down and start working. I can’t even explain it, It feels like it would be mentally overwhelming but I also feel like there’s a physical force holding me back and I start to do it but then say no I just can’t. Nothing about the work is overly difficult for me or boring. ( I’m an investigator that looks into the social history of Defendants who have committed violent crimes)

I’m running up huge credit card debt because I’m barely making anything even though I have court funding authorized for my cases. I just have to do the work!

Anyone else ever get a block like this? I’ve tried doing little bits for short time, telling myself reasons why I have to make money, just can’t get myself to do the initial sit down and start. Not sure if it’s cuz I have no one pressuring me so I slip into my depression and can’t find the strength and desire to do it or just what it is.

Any /all suggestions or insight welcome !
Ps I can do physical things, , just painted bathroom this weekend, put up Christmas lights, decorated tree, shopped for Christmas, made thanksgiving meal, went to grandkids activities etc but the thinking mental part I feel like a force is stopping me!

have you tried soft background music? (the kind of stuff you might hear at a doctors office)
it won't distract you from work, because the music is slow and instramental.

no risk in singing along or getting carried away with the music.

if it works for receptionists at doctors offices, and works for patients, it might work for you

Thanks yes I have. It seems to help a little bit not enough lol
