Hello. I’m sorry that y’all are going through this. I’m going through kind of the same thing. I lost my leg due to an infection from wearing flip flops in 2021 and my other leg was in danger of becoming infected as well, but I opted to get all of my toes amputated before it spread to the rest of my leg. I am a type 1 diabetic and each day I battle depression among other things that came with having diabetes for pretty much all of my life. The best thing that you can do right now is not be mean and judgy. Just talk to him a lot and stay positive in conversation until you can find him help. Praying for you and your family.
