Does anyone here have type 2? Can you tell me about it? Pretty sure my Dad has it. I've been doing a little research on it but I'm still not sure about how bad it is or not.

I know it's not the same disease as type 1 but my brother has that and I know it can be life threatening if he doesn't take care of himself. (which he does not) So I'm worried about my dad. I don't want anything to happen to him. I'd at least like to know more so maybe I don't have to worry so much?
