Most people reading this may not know what a diabetic ulcer is.
Let me lay it out like this: Type 2 diabetes is typically caused by too much glucose (or simply too much eating,) which makes a person intolerant to glucose. This can lead to something called polyneuropathy (numbness) and in turn leads to a person who cannot feel their feet making them highly susceptible to injury. The ulcer that forms on the foot, caused by poor care, can get infected. That infection can get bad enough to where your foot has to get amputated or it would kill you.
Emotional issues are like this… daddy issues are like this. Starts with small bad habit that perpetuates into disaster.
