ELI5: How exactly is type 1 diabetes different from type 2 diabetes?

I was diagnosed with type 1 a few weeks ago, and my specialist tried explaining it to me but I still don't really understand the difference.

With Type-1, your pancreas doesn't produce any insulin. Frequently this occurs when your immune system overreacts to an illness & attacks your pancreas.

With Type-2, your pancreas produces an insufficient amount of insulin and/or the insulin it produces is ineffective. Frequently caused by diet and/or a sedentary lifestyle.
