Hi...you have to withdraw from SSRI's slowly but cutting the dosage down every day for several weeks, then start taking them every other day until the withdrawal symptoms are tolerable. I have been weaning off Lexapro for over a month. I thought I could go from 10mgs to 5 then 2.5 in a week...then didn't take any for three days and had all those symptoms you described so now I am back to slicing the pill a little more every day until there is none. The brains zaps were the worst...felt like my head was full of water and when I moved my head or eyes it would make a 'wooshing' sound...and a zap.
I don't know if you stopped cold turkey from your post, but it sounds like you did. You may have to get another prescription and go off slowly. You aren't sounding ridiculous...you'll find many posts from people who have had problems trying to get off these drugs!
