Diabetes care around the world

Hi, first time posting so I hope I'm not repeating a past topic.

I have Type 1 diabetes and live in the US. I was lamenting to my partner about how expensive insulin is here, and I was curious if it really is that expensive everywhere in the world? And how do you get your diabetes supplies? How does that work if there's free healthcare? Do you not have to pay for your pump supplies? Is it not as expensive in your country as it is here in the US because of private insurance? Do you have to go through middlemen (Edgepark, Byram, etc.) to order supplies, or do you just deal with the company directly?

Genuinely curious. Thanks!
