I am going to have my pancreas removed in a few weeks. how will this affect me?

Depends: Whole pancreas or only part? If whole pancreas, you will need to take pancreatic digestive enzyme pills with food, and you'll have to take insulin. Total pancreatectomy diabetes is like type 1 - no Insulin is made, and Insulin must be delivered at a low level round-the-clock, and in a burst before meals. If that's the case, you should see an endocrinologist because it can be a challenge.
