I believe I need my gallbladder removed

[stuffed_killer_monkey666]

Symptoms:
I cannot eat a thing without throwing up (also heave bile id I don't eat at all), I experience constant searing pain in my right side a little under my rib that only eases occasionally but never goes away (can sometimes feel it in my shoulder blade; can be described as a throbbing, someone pudiarrhoeaeir elbow in or a knife has been stuck in and twisted). I also experience constant cramping, gas and diarrhea.
Reason to believe:
I have a family history of this and my hormone levels have recently elevated due to the discovery of my hypothyroid; I take tricyclin and levo-thyroxide.
I have tried many medications and adjusted my diet (even to B.R.A.T) but nothing helps to even ease the vomiting. There is 100% no chance of pregnancy. I have been seeing doctors for months trying to find out why this is happening but feel I have been getting the runaround. I will try to leave out my dissatification with them but this is progression of my situation:

October 23rd 2009: I begin vomiting at least once a day. I figured I had the flu.
Novemeber 18th 2009: I am diagnosed with Bronchitis and banned from work (apparently I am not eligable for EI or anything else so my folks help cover my bills).
December 25th 2009: Discover my mother, grandmother and grandaunt all had to have their gallbladders removed for the same symptoms. Vomiting and breathing have worsened with addition of muscle pains (visited the ER several times but was sent home.)
January 21st 2010: Have an Ultrasound (only a fatty liver found). The procedure was excruciatingly painful as they preformed the procedure (I literally tore up the sheet on the bed). From this date I begin experiencing the seering pain.

Also, since this began last October I have lost 54lbs. I was originally I am 5'7 and was 205lbs but am now 151lbs to this day (Sept 7th). My doctor keeps trying to reasure me that the weightloss is good, but I continually stress to him how I can't even be happy with losing so much weight with the pain and vomitting I have been experiencing. I would rather be exercising and eating right if I wanted to achieve weight loss. :(

March 2010: Diagnosed with a bad allergy to dustmites and will begin immunization when I can afford it (to this date have not made enough money to cover my bills/food/rent until I am cured of my other problems.)
April 6th 2010: I have an Upper Endoscopy with nothing found. Doctor tells me to take Nexium (which my family doctor already told me not to take because it was making a lump in my throat.)
April 30th 2010: Must return to work (parents can no longer support me.)
July 20th 2010: After occasional check ups my Doctor finally arranges catscan while informing me my iron levels are very low.
August 9th 2010: I have my Catscan.
August 12th: I recieve a phone call from my doctor saying the scan showed Diverticulosis (which is good to know) but doesn't explain the vomiting and pain. My gallbladder was not shown; an appointment is set for the 16th to discuss my results. After researching it, I will be asking my doctor for several tests such as an MRI for my gallbladder.

Results:
My symptoms continue. I have lost 40 pounds (with a hypothyroid), my hair is literally going grey from vomiting and I have to take tylenol every 4 hours in order to function. I continue to get low hours at work due to my illness. I have told my doctors at EVERY appointment about how much Tylenol I have to take, and their response is if I am in that much pain I should go to ER, but I have been to the ER several times and they always tell me there's a problem but it's not immediate enough to fix so they send me home. I'm scared that my liver is being seriously damaged and I am constantly having fits of crying. I don't remeber what it's like to NOT be sore.

I find it surprizing that after research their are tons of other people out there who are treated the same way on this subject. Am I so wrong to believe that my gallbladder is the cause?

I had my appointment yesterday; my doctor is going to try and arrange a Endoscopic Retrograde Cholangiopancreatography (ERCP) but not an HIDA or MRI. He also said I shouldn't worry about the amount of Tylenol I'm taking because a person can take 3000mg a day and I'm only taking 2500-3000mg a day. The Catscan said it found nothing remarkable but Sigmoid Diverticulosis (which wont be treated). Does this mean my gallbladder is not the issue?

Sept 7th 2010: I was given a MRI instead of an ERCP to have it come back normal. my doctor's secretary informed me that I need to be reassessed. Should I continue on with tests or suggest exploritory surgery? I'm literally about to lose my apartment and my doctor's are just twidling their thumbs. Would I be wrong to ask?
