Gallbladder? I'm At My Wits End.

I started with nausea about 2 1/2 weeks ago, pretty severe that the thought of food made me want to go throw up. That slowly has dissipated only over the past few days but now I have a constant pain where my gall bladder is. It's waking me up at night..Sometimes it dulls but it never completely dissapears. I've had two ultrasounds and numerous blood work tests and both have come back perfect. Which is not suprising b/c my blood work was perfect before I was rushed in for an emergency appendectomy. In fact i've never had bad blood work at all. I have a history of tachycardia, mitral valve prolapse and migraines. I've been to the er three times in the past 2 weeks for this and have gotten a different answer everytime, one time..I didn't even really get an answer. I was told heartburn, I know what heartburn feels like, its' not heartburn, and then I was told constipatition, however my bowels are completely normal and i've gone atleast once everyday, normal stools. Maybe a little lighter than usual but thats it. They said that my x-ray showed stools in the lower right quadrant and that maybe they weren't able to get passed scar tissue from my appendectomy in january. However, on the discharge papers he put constipation. If he thought I had a blockage he would have admitted me, not sent me on my merry way with more pain medicine. Then it was so bad that I went back again last night, and begged for an emergency hida scan, although i'm pretty sure it's going to be normal, thats the way things seem to go with me. And the dr again diagnosed me with, "abdominal pain" how can that even be a diagnosis? Thats the symptom!!!! I feel like I know more than these doctors do, and thats scary! I don't like taking pain medicine..And she said, "well its' going to be a long 2 weeks until your hida scan if you don't take pain medicine" I saw a gi on monday, the nurse practitioner, and she ordered the hida scan scheduled for the 16th! Then, I have a follow up with the real dr, on the 28th. My problem is that i'm scheduled to go the hatteras, nc on july 15th. Even if I could get surgery tomorrow I would not be healed.
Sorry it's so long, and not very well thought out. I'm just very angry right now. As of right now my course of action will be to follow through with my hida, get my results do my follow up and in my perfect world I would hear that its my gallbladder and have it removed after vacation. But i'm pretty sure i'll hear you're fine, blah blah lbha you're too young. And then I will have to schedule with a surgeon myself.
I'm so confused & angry. I don't trust any of the doctors i've seen. I feel like my gallbladder is going to blow up. It hurts worse than my appendix. The only good news i've heard is when the pa said, it's dfeintly your gallbladder that's causing the pain. But thats it!
Any words of advice would be greatly appreciated. I've read other numerous posts where every test was normal & then when they finally had it removed the gall bladder was diseased.
Thank you,

Ps. My appendectomy was open surgery, and my symptoms were very akward for it. I actually saw the same np 4 days before my surgery b/c I was having severe stomach problems for about a month prior. Everything I ate would either come up or down within minutes. I had narrowed down what I could eat to turkey and mcdonalds (go figure). My appendix was in the wrong spot, hence the open surgery. The gastro np was like haven't I seen you before..I was like yeah, you said, "give it a month we don't want to do anything invasive" and then I told her about my surgery and she was like, "i feel really bad" I think thats the only reason she even schedule the hida, because she screwed up before! She wasn't even aware that an appendix could be in the wrong spot.
I just want to scream!
