Going on Insulin Pump!!

Hi! I am a type 1 diabetic for over 30 years now. My endocrinolgist has scheduled me for an insulin pump. My husband and I will be attending a pump retreat the middle of October.

 I am both nervous and excited at the same time. I have been taking shots for so long now, that it is nothing to me.

 Can someone please tell me what I can expect with the pump? I already am counting carbs and keeping a food diary and tracking my bloodsugars. Please just tell me more about the pump and things I will need to do.

Thank you very much in advance for your help.
