Hi Caley,
Great to hear your enthusiasm. The only way to go onto pump therapy is through your diabetes care team. There are a number of conditions you need to satisfy and they will need to assess your readiness to go onto a pump. Ask the question as soon as possible.
Regarding which is better... it depends on the individual. I'm a pump user and much prefer it to injections, but there will be people who don't get along with the pump too. It isn't easy either... most of the same considerations as when injecting, i.e. carb counting, special consideration around exercise and in fact the features of the pump mean that your understanding has to be that much more detailed. E.g. you program different basal rates for different times of the day depending on your needs.
Best way to find out is to keep asking questions though.
Sam.
