How long is normal before surgery is performed on a gallbladder disease?

I was diagnosed with a malfunctioning gallbladder three days ago. I have been in severe pain with nausea, vomiting, diarrhea, and constipation for four weeks. I have been in the ER at the same hospital 3 times in the last two weeks and each time I go its a 6 to 9 hour wait and the doctors just give me 20 pain pills and send me home, saying if the pain worsens or symptoms change to come back. The pain has steadily increased and I have lost over 30 lbs within this time span until 20 5/500 vicodin last only about 3 days (I take two every four hours just to lessen the pain to the point of being able to move). I set up a surgical consultation today, the 8th of march, and was told the earliest appointment for just the consultation was March 29th, three weeks away. I have no insurance, but have received a discount through the hospital, but this leaves me with no primary care physician and the earliest date to meet with a potential primary is in late april, way past the point where it will do me any good for this. I am sick, unable to sleep or eat, and in constant, debilitating pain and am not sure how I am going to make it another three weeks this way. Is it normal to have to wait this long between diagnosis and treatment for gallbladder problems? What can I do to speed up the process besides calling every day in hopes of a cancellation?
