Happens to everyone from time- to -time, nothing wrong with taking a break

you just need to tell yourself it is ok . Sometimes when you get overwhelmed you get stuck in that mod and it just seems like the hole gets deeper by the day. As others mention maybe start something small/fast and enjoy the feeling of accomplishment.
As for the clutter/messy sewing rooms- don't look at it as a WHOLE room that needs fixing- look at it as a small section. This shelf needs folding , this drawer needs organizing, one thing a day .
Rome wasn't built in a day - take time to stop and smell the roses , enjoy the small victories - don't make it a "Chore" , relax and enjoy , Make it fun again
