Hi Sam,
I'm so very sorry you're feeling in such a dreadful place right now.
I'm not sure how long you were on the meds which caused such a bad reaction and don't know if you're on any other ones now, but considering how you say you're feeling I absolutely agree with what ginnie has said about possible negative responses to any meds that you may still be taking now. I suggest you find urgent professional support - like right now.
