It well could be, also sorry to mother you lol, but did you speak to your doctor before stopping? I'm just saying because some of the worst side effects can happen when you just come straight off without tapering. It might be worth going to your doctor as they will likely have a good idea if it's the meds.
Though I can appreciate maybe worrying and wanting to get off them quick if you feel they were having an effect like that.
Obviously raging is not good, but do you think maybe they were working and helping. I can only speak from my own experience, but I have found after long periods of time, when I do get a medication which works, the way my feelings come back can be really intense and not very pleasant. Do you think that could be the case for you bud? I mean have you had any other intense emotions? Or is it simply just a feeling of rage?
