WOW, hon I feel you pain! If you are in the middle of a really bad attack you need to be seen immediately. Since you didn't say whether you under a docs care for this, my advice is that you need to be seen by your doctor pronto. I have been where you are with the gallstone attacks and I know they hurt worse than childbirth. Honestly, the only relief is through pain meds. Is there someone who can take you to the ER or urgent care? Can you get someone to stay with your daughter? You need the type of treatment that you can't get from simple answers over the internet. Go take care of yourself and I hope you find relief from your pain quickly! Good luck!
EDIT: OMG, whatever you do, do NOT drink the coke as someone suggested here. That will make it hurt ten times worse. You need medical intervention b/c it can be dangerous to fool around with alternative preparations and placebos. You can actually harm your organs with some at home treatments. Please just be careful whatever you do!
Had gallbladder removal in 2001, had lots of pain prior to that which turned out to be small stones.
