The symptoms you describe could easily all be attributable to alcohol withdrawal, but it would be irresponsible for anyone here to say categorically that that's what they are.
The thing about alcohol withdrawal is that it can get worse -- more severe, with new symptoms that last longer -- with each successive detox, sometimes quite suddenly. Do a quick search on this site for "kindling" if you're interested in learning more about it.
The nice thing is that you never again have to feel as you do right now!
Welcome to SR! Hope you'll make use of the site as a resource to help you stay sober for good. I promise you'll be glad you did!
