I’ve only been seriously drawing for about 7 months, but I have come to a point where I’m rarely drawing for myself. I still complete owed art, and such, but I have a hard time getting myself to draw my own characters and such. I have no idea why. I don’t know if this is what would be considered “art block”, but it’s frustrating. I want to draw my OCs, but I never actually want to follow through with it. What I might try to do is finish up all my owed art, and challenge myself to start/finish at least one personal piece a day, whether I share it or not.

It sounds like stress related to doing work. "Why should I draw my OCs when I have work to do" feeling? Finding a Rhythm between both can be quite hard. Have you any time when you don't have any Queue in a while? One thing I suggest is to try out something Audience interactive with your characters like Character asks or involving your audience with your artwork in some way with your OC talking, responding, interacting with them/ the viewer.
