Hahaha! This is a bit too relatable! I wish I could give you some advice, but sadly I ain't found the answers I'm looking for. What I can say is artistic abilities often feel like sandcastles. Everything can be going good until a wave comes by and knocks it all down, and while that can be frustrating, I've found that it gets easier to rebuild the sandcastle each time.
Try to take it easy on your break, and don't do what I do when I take a break. Don't torment yourself by thinking about how you could use this time to be drawing. The whole point of the break is to relax and regroup, ya know?
I like your stuff and look forward to your return.
