No one on this forum can tell you or advise you or diagnose anything when it comes to your own alcohol withdrawal. But as you have just found out alcohol withdrawal can be quite frightening and dangerous so if I were you I'd be seeing a doctor sooner rather than later.
To me, it sounds as though you've relapsed because you were discharged but did not have any kind of solid recovery plan at all.
I think you have two things to address here. 1) make sure you aren't having any kindling or dangerous withdrawal symptoms from a doctor and 2)come up with a support team and solid Recovery Plan.
And stick around here! SR is a great place
