Though not an SSRI, Welbutrin did something similar to me, mostly hypomanias (and on dysphoric mania) more than depression, I was on it from November 2015 - February of this year... Could tell if things were situational of if I was in an episode until I looked back and realized I had no real triggers other than for the full blown dysphoric mania (that we stress.triggered).

But I'm sending you hugs
