However, let me warn you that this will venture you into concepts of human body you have likely not heard of and which has not been studied extensively by modern medical science. However, it's heavily researched and applied at least for thousands of years in India etc.
>>> Depression is a state of mind. It is not a physical ailment; it is not a neurological disorder and it is rarely a malfunctioning of the brain. It is strictly a condition of the mind. And mind pervades your whole body and beyond. It is for this reason that pacification of the mind calms the whole body just like its restlessness upsets the whole system. Severity of depression can be ascertained from the symptoms of the patient. While I am using the term patient, that truly is an oxymoron. There really cannot be a “patient” for depression because it is not a “disease” that one can suffer from. It is simply a mismatch of the colliding psychic imprints (vāsanā) also known tendencies of the mind. Mind cannot malfunction for the true nature of mind is pure bliss (ānanda) and beyond all subjective characterizations and dualities (dvanda).

A pertinent question: what causes depression? Depression is a state of mind. It originates in the causal body. The mind has become a victim of its own latent tendencies. It can happen from curbing your desires or an unfulfilling life, both of which are caused by ignorance of the conditioned mind. A lot of people lead an unfulfilling life; some choose to ignore the voice of the soul while many others drown it in material pursuits. But, one day it catches up.
....
If you are not taking anti-depressants currently, half the job is already done. Please do not start taking such pills. They are soporific substances designed to artificially pacify your brain creating the illusion of a calm mind. Gradually, their dosage needs increasing as your brain gets used to it.
To not only completely get rid of depression but feel fitter than you have ever been, you need to cover all three aspects: body, consciousness, and the soul. <<<<
