Hello Friend, Good that you are seeking a help. As you have attempted different approaches already and still not getting a relief, let me share you a different perspective for your problem through Ayurveda angle.  Typically low mood or any depression kind of symptoms creates in mind if there is an imbalance of water energy in the physical body (called Kapha in ayurveda Vedra terms). As body and mind are interlinked, some time bodily issues also cause you mental imbalance and visa versa. Solution for such problems are either  home remedies or dietary or lifestyle changes and few massage therapy. However it need detailed evaluation to of your body and mind constitution understanding.. I am also an ayurveda wellness counselor and you can reach me online through Practo for consultation.

I think u may have issues in your past which hurts you. If it's true they may be affecting your life. Find a EMDR therapist then. You will get well.
