I had a diabetic coma when I was 21. I had been rock climbing all day and in the evening had too much insulin and too little carbs in an evening meal. Away from home and sleeping on a floor I went into coma. The ambulance were called and it took a large effort to keep me stable and inject glucose however I went out from that point and was out for three full days in hospital ( brain tests were done in that time and found I had not hit my head climbing etc). I woke up not all together with this really weird need to get out of hospital. I discharged myself, walked 5k through a strange town with no money to a friends place who gave me $20 to get home on a train. Four hours of travel later I arrived in my home town totally messed up in my head, my arm aching from the struggle I had given the ambos with that intravenous needle for glucose five days before and still not having my head together.
Since that time (20 years ago) I believe I have had trouble concentrating, often need time alone, have small friendship groups and have lost friends too as they believe you character has been negative. In hindsite after battling through my diabetic life and surviving ( I have a pump and perfect hb1cs), I still feel that there are some unaswer d truths from this coma and the aftermath I went through. I was so stupid back then but as I said I was not right in the head. I am married have tow great kids and a stable enough life so I have bluffed my way through what could have been a catastrophic episode.
