Is there any way to travel the world/backpack while being a Type 1 Diabetic?

Well, say I wanted to buy a RV and travel the world and needed insulin, is there any way I could obtain insulin around the world? Or if I ever wanted to backpack around the United Kingdom. These have always been life dreams of mine but now that I'm diabetic, I feel like those dreams are down the drain. Any ideas/suggestions that might help me keep hold of these dreams?
