Hi there,
Start Vit
B12 supplementation. Take T Subneuro (it's a sublingual mouth dissolving tablet, not to be chewed or broken) everyday for 60 days.
Eat egg whites and lean meat (fish and chicken) regularly.
Apart from this, I'll recommend you to consult with a psychiatrist in person to evaluate your symptoms of depression in detail.
Next Steps
Consult with a psychiatrist.
