Hi I went through the same thing I was on pred aswell and had alot of side effects aswell!! It's really horrible going through all this but just know you will get through it in the end
I went off pred onto a medication called Imuran and pentasa for UC and it has been a life saver for me! I have no symptoms what so ever and my tummy is feels perfectly normal now. Just hang in there because everything will work out soon!!
