I’m sad to hear. There is the possibility that it is just a fluctuation that will even itself back out. There is a certain amount of highs and lows that is to be expected and even if it goes beyond that it can bounce back without intervention. We can be resilient more than we expect.
Maybe try Turmeric. It is a mild modulator of both serotonin and dopamine. It’s supposed to get better absorbed if taken with pepper which can be bought as bioperine supplement.
Curcumin is the extract of the main active ingredient in Turmeric, but this might be too much to start with. If you decide to try it I would go for Turmeric. Swanson has Turmeric with bioperine.
