Heya. I've been diabetic for 12 years and had a pump for 10 of them. I think it is the best tjing ever and woyld never go back. Some people don't like them but they are very few and far between. Even if injections are working for you, a pump might be better and might give you a better quality of life, speak to them and see what they say. I find it gives you that freedom with eating and sport. Also when you're ill you can easily change your basal to help with high sugars.
If it is something you want to try I would push for it.
If you have any questions about using or living with a pump just ask xx
