Pancreas causing pain and weight loss / gain ?

hello
i have seen 13 doctors 5 were some kind of specialist. i have had 2 ct with contrast scans, 2 ultra sounds, 2 gastricscopes, and enough blood work to build a new healthy me. ALL the doctors refuse to consider my pancrease and have settled on either its in my head or I have acid reflux. OK here are my symptoms:
Begining June 2009 my sugar was high and doctor said i had type 2 diebetic but we would try and monitor via diet. sugar is fine now?
-in 5 weeks i lost 30 lbs doing, and in the next 2 months 25 more. I had severe pain in lower and upper abdomin, right back under shoulder blade, pain upper left and right abdomin. laying on back,or side very painful. I hurt so much you could not touch me. By December and many Doctor visits I started to put a bit of weight back on and the pain was managable but still there, but February the pain was a 1 on a scale of 1-10 10 being high. I though i could handle this...BUT
begining in May
PAIN - same places rated as 7
BM - diarrea again or thin colourless poop
urine - dark and feels as if I drain every ounce when I go
can't lay down
can't stand water,dariy,meat,sugar,or even veggies. Doctor put me on Nexium nothing has changed.....HELP i have lost 7 obs in 5 days
