Well I was diagnosed years ago with it actually haha. Though it was never this severe. The way it manifested back then was far more emotional, it usually never fucked with my motivation or energy this hard, I would just have a week or two of awful venting and bad sketches, then all was well after that.
For a good 2 years I had no symptoms at all, and I had stopped taking the medication a little before that since I felt that it wasn't needed?
Anyhow it seems really odd for it to come back in a completely different, and somehow more debilitating way.
