Diabetes is a disease that is dreaded by many, but it can be controlled if recognized earlier. Yes diabetes can cause anxiety and depression and other illnesses. This comes about when people really don't take care of themselves with the doctor's orders. It is very likely that when someone is diagnosed with diabetes that's when anxiety sets in. Many people start feeling incapacitated even before anything major happens to them. They start thinking about the treatments and that can be very draining. When you start thinking about that, depression sets in, making you feel hopeless. But I think depression comes in later when diabetes has progressed on for a while. Some people end up losing limbs from diabetes and when that happens it reduces their self-esteem, their hope is stripped off because now they are thinking, I was able to do certain things for myself, now I have to rely on somebody else to do it for me. That is quite distorting, it's discouraging, it feels like a part of you has been taken away not because you warranted it but because of its just the nature of things in our lives. Shock also grips them when they find out that they don't have a limb, some may survive that, but some people don't recover from that shock and in a short time they pass on. Having people there by their side to encourage them is very vital. Following doctors, orders can save us from certain illnesses don't take them for granted.
