I am so sorry you are struggling. I think you might want to run this by your pdoc. I say this especially since you are noticing this while stopping a medication. If you need emergency help, then please don't wait and seek that out. I had a similar type of reaction while stopping Lexapro, although the Lexapro had me in a mixed episode, stopping it put me in an extra dark place for awhile. I will say within the week the worst of it was over. Hope this passes quickly for you, please stay safe and get help if you need it.
