You are not a bad diabetic! You are a person that needs help coping with the depression and with the disease itself. It wasn’t too long ago I felt like jumping of a cliff because I couldn’t understand why my body was declaring mutiny on me.
Please if you need to talk I am available. Please try to find a counselor or a Diabetic Educator or clinic to help you with both of these conditions. Cutting is not going to make your situation better. Cutting yourself on the hipbones has got to be painful too. Please get some help
