Non-Medication Treatments for Mental Health?

I’ve been recently experimenting with food as it gives me sleep attacks. I’ll eat snacks and small meals during work hours. I try to stay away from carbs and fatty food as much as I can.

Low carb, low sugar diet

One of my worst symptoms is psychological: guilt. The guilt of feeling like a burden for being so exhausted, needing to rest and sleep so much and so often, not being able to partake in activities like others can. So for me, the best treatment was Dialectical Behavioral Therapy (DBT) because it allowed me to change my thinking in this regard and reframe my thoughts away from guilt and toward self-understanding and self-kindness.
