I'm thinking about ways to implement other mental health conditions. Generally staying on the lower end of severity because I'm more familiar with it, but you could represent anger issues by having skill checks when other characters do seemingly innocuous things, and if you fail all the dialogue options are bad. ADHD could be done with a required mini game of correctly identifying all the steps in a process and having cooldowns between them to reflect executive disfunction. Hyperfocus could be implemented with certain objectives not being completeable, or even showing up in the game anywhere outside of dialogue, until one is. Seasonal affective disorder could be shown with a characters stats just drastically dropping when the seasons change, and the HUD colour scheme becoming more muted.
