this will take a while but it will help your brain regenerate its neurotransmitter supply. any more direct drugs will cause a release of, or alter the reuptake of, a neurotransmitter, which is more likely to decrease your neurotransmitter levels in the long term. so the best advice i can give you on top of this is to stay away from dopaminergic and norepinephrine-releasing drugs. especially amphetamines and other stimulants, which cause the most profound effect. opioids will lower your dopamine long term, and increase your norepinephrine levels, which may sound good but its a pretty horrible anxiety.
