It's pretty much the same as serotonin. It will work to increase serotonergic activity (which could very well work to make you feel better), but it's quickly metabolised and no longer works, like serotonin would be. It's probably better to use a serotonin precursor and a way of inhibiting serotonin recycling and metabolism/removal, using an SSRI or MAO inhibitor.

But you might want to try an atypical antipsychotic instead or together with an SSRI or MAOI.

Have you tried taking an (atypical) antipsychotic?

Edit:
I was thinking, maybe it is a good idea as some kind of shock therapy.

(And I see you take Latuda.)
