I would see a different doctor soon or, at least get a second opinion. Not knowing what dose you were on and just assuming you were started on prednisolone
either Iv or pill form in the hospital until the time it was discontinued without taper
, I would put my worry out of my misery by seeing another doctor. Especially, since you described "horrible withdrawal symptoms" (again, not knowing what they are) besides the anxiety you are experiencing, which is also concerning.
