Nah this is pretty average for ADHD too. Maybe not sinking a fuckload of money (I guess it depends on the person) but hyperfixations are a thing. Get really focused on one thing because it gives you dopamine so you sink more and more time into it until no more dopamine. Suddenly it becomes a chore to do like everything else, you feel betrayed, and end up in a feeling of malaise trying to find your next hit of dopamine.
