depression is a known thing to happy after 70 years , at the age of 80 years , our medical books say , use as less medicine as possible , as your body knows how to remain in harmony for last 80 years
Serotinin is a happy
neurotransmitter Dopamine is energy neurotransmitter
GABA is a sleeping neurotransmitter
You dont know which of the neurotransmitter is less in your body , as taking extra serotinin can dissrupt the neurotransmitter harmony , and can cause increase suicidal tendency

What you need is , friends so that you can ventilate , get your self busy in any thing you like ,
psychiatric counselling , if required serotinin drugs
