I'm so sorry you're going through that. I was on Paxil and weening off it was a nightmare! I would be dizzy all day long. Not even sure dizzy is the right word..it was like every time I moved my head or blinked I would feel this we're shudder in my head and the closest thing I can call it is dizziness. It sucks. And being more irritable and crying, yeah.
I hope things get better soon. I know it's hard. Here if you every want to talk.
