No offense, Bro,
I understand that depressed people can have a
profound understanding of matters that
others prefer to gloss over...

NONE-the-LESS,
understand that even small furry animals in
labs exhibit DEPRESSIVE MANIFESTATIONS when Vitamin D levels 📉.
Likewise Zinc.
Being OUTSIDE in DAYLIGHT > 15 min.s/ day HELPS w/ Vit.D (may be why "homeless" folks in California seemed immune to☠️ by COVID-19).
Zinc's in some vitamins & lozenges for fighting viral infections.

Care from real humans also essential...

Best Regards,
