Most compounds nominally prescribed for mental health don't actually improve mental health in a substantially performative way, they just turn the subject's brain off so they are easier for their handlers to wrangle. It's like solving the problem of wonky power steering by cutting power to the steering.
The field of treatments that actually are performance enhancing is small, but there are some modalities that exist (like moclobemide, tianeptine sulphate, phenylpiracetam, bromantane, omberacetam, intranasal insulin, or plain old lithium), which would be preferable choices for assistance in ameliorating chronic negativity or and anxiety issues.
