Oh no! I am so sorry to hear that!
Mentally, the best option would be to take a break... but if you really need that income (and I am guessing that you do), maybe try to make adopts?
It might help if you are following what you imagine in mind rather than trying to catch up to demands...
This is only a suggestion, and I do not know if it will help. I hope you will feel better soon, deciding if you want to continue being an artist, take a break, or stop.
