So that's the problem. Might you suffer from anhedonia, a common part of depression? It can also be ADHD-related. ADHD is a common co-diagnosis of autism which is a common co-diagnosis of using HN, and ADHD basically means your reward system is messed up on all axes, not just the ones that cause AD and H. I'm not diagnosing you, just throwing out words you might possibly look up.

Don't assume it's only depression, check your testosterone levels etc., probably best to just get an endocrinologist consultation.

If you're tired and don't have energy you'll also feel depressed but that doesn't automatically mean you feel tired solely because of depression.
