Whats the quickest way i csn get off Prednisolone?

In 3 months into what was supposed to be a 2 month taper. Started 50mg in hospital . Im down to 20mg today and i am n hell. I look like a corpse, i have. 2 black eyes and open cuts on hands that havent healed in 2 months. My arms and legs are covered in red welts from mosquito bites that inflame and wont heal. Cuts and grazes on my knees from skateboard injuries i did years ago have resurfaced and become open sores. My face imhas swollen up. My iphone doesn't recognise me. On top of that prednisilone has done nothing for my UC, absolutely nothing. In the worst flare since i was diagnosed. Im so angry at this horrible drug

I need to stop taking it as soon as possible.. I dont want to hear 'talk to your doctor'. I need fo hear from anyone who has tappered quickly for whatever reason. Please

Can i halve the dose each day and be off it in 4 days.? Any suggestions
