Based on my experience coming off an anti-depressant, a lot of that does sound like withdrawal. Thank goodness for the internet or I would have just thought I was going insane. Some of the symptoms were too bizarre to even describe, but fortunately (or is it unfortunately) I discovered a lot of people went through the same weird symptoms coming off that drug. Dig around online somewhere & see if you can find out for your drug. It will help you know you're not completely nuts.
Good luck, we're routing for you!
