If the gallbladder has a function in my body, will I be okay without it? 

Yes, you will be okay without it. The gallbladder works as the storage center for bile, but fortunately, bile is made in the liver. Once the gallbladder is removed, your body adjusts to no longer having a storage center and instead sends the bile straight from the source in the liver. For the vast majority of people this means that within a few weeks, your ability to digest will return to normal. For some people there is a transition with some bloating/loose bowel movements for a few weeks after surgery when eating fatty foods. If you are managing loose bowel movements after gallbladder surgery, it can be helpful to use fiber powder (metamucil or citrucel) while this remains an issue.
