I am sorry you are experiencing these intense withdrawal symptoms. The most important thing is; it will get better, it just takes some time!
Like @guava378 said, there is a window of opportunity for reinstatement, after some time the probability of it helping diminishes. Unfortunately we don't exactly know how long the timeframe is for different people. If you want to reinstate consider only taking a very small dose and holding it instead of going back to the original dose. I hope you get better soon, for me and a lot of people the windows of feeling bette are a good sign.
