Aww, take care of yourself! :)
I'm sorry to hear you're going through such a rough patch. I'm just a peasant, but, I hope my words carry weight with them. You are easily one of, if not my favorite artist, your style and varied expressions, wildly different characters are all so amazing. You are an amazing artist. Always.
Take care of yourself mate! It's important to step away every now and then to recharge.
Definitely sounds like burnout. I recommend a break and not trying to force it until you feel that real drive to create again. Art is in your blood, so I have the feeling it won't be long.
No matter what you do, we’ve got your back. Your mental health and well-being always comes first. Thank you for all that you do, and for being you!
*hugs* you do you and whatever needs doing to be good with yourself.
