It could be ADHD too. It, other neurodevelopmental disorders, and affective disorders can affect how one feels about just about anything.
I have ADHD and I derive nearly no pleasure from “a job well done” unless the outcome is directly and fairly immediately beneficial.
Project completed at work? At most I’ll be relieved it’s done unless it shows off my skills, which I like - dopamine!
Baked a cake? For myself, fuck yeah - dopamine! For someone else and I don’t get any? The forecast shows a light chance of a low pressure dopamine system entering the region this afternoon, depending on how much I like the person.

























You just have to push through! Willpower!
Just kidding, I hate that shit. Sorry to hear it, I can’t imagine how difficult that must be. I’ve never tried meth. It sounds like it’d be too much of what already works for me.
