How do you deal with the withdrawl scare, by th socially and physically?

i got 5 days clean and started hallucinating wildy, like scartiest shit ive been through. i managed to get myself to a emergency addiction center and spent the night getting shots of B1 and anti psychotic, benzo etc and once i got out i got scared because i noticed some hints of audiotoral hallucination again, especially fans and stuff, they sounded like radio being played. im over worked too but i started drinking again in fear for my health because i kept having shakes and shivers and cold sweat, i didnt sleep or eat for two days until i started drinking again. im very high tolerance, so i dont even get drunk i just get normal, same amount would probably send some people to emergency care to get their stomach pumped. my liver values are getting bad, and i want to quit but im so scared of the withdrawl agony or potential danger to my life by quitting too fast, but i know I am also slowly killing myself.

im sober now for two days and last night was like going to hell, i even saw demons taunting me in my dreams and i woke up drenched in sweat every 30 min, and i cant be put in overnight again because of work and they need to see my medical journal to be on paid leave and HR are notorious for gossiping.

are there any tricks to tapering on your own or supplements that help? our healthcare rarely help alcoholics, they basically send you a bill and write out some campral and sleeping pills.
