Shock returned and dealing with panic

After having the huge shocks controlled and non existant (the burning unfortunately has not been controlled) since June thanks to 1200mg of oxcarbazepine, I had one face shattering shock return over the weekend. I believe it is because I was foolish and tried to reintroduce half-caf coffee over the last 2 weeks. I am devestated. The burning is worse than ever. Now back on a depressing liquid diet because I am terrified to eat solids. The panic and defeat I''m feeling is unreal.
