^^ Yup, that is the number one reason causing it. It can also occur from a doctor over prescribing, or miss-prescribing an SSRI. I think the risk is lower with RIMA's, and also if you are taking lower doses of SSRI's, none the less, it's nothing to fool around with.
I've never heard of taking psychedelics alone causing it however. I have done a lot of research in regard to RIMA's and SSRI's, but unfortunately there is very little out there.
Oh, and yes. Serotonin boosts can help with general depression and anxiety, but like anything, too much can cause an OD.

…is DMT dangerous? The answer is only if you fear death by astonishment… [crowd laughter]… Remember how you laughed when this possibility was raised… a moment will come that will wipe the smile right off your face.
