Burnout? Anxiety? Overwhelmed? (Patreon)

Drawing I made after my today's night experience, I am okay, but these feelings come quite often recently, I am unsatisfied with lot of my work, I think I can do better but can't manage myself to do it, I get so easily distracted by thoughts and my surroundings, somedays just ending up staring at almost blank screen for hours. Not sure what's causing it, and these moods tend to come and go, seemingly at random. My sleep is broken and I am in this kinds of unpleasant cycle.
