I live alone and have another condition as well as diabetese. Sometimes I can control it and other times not, My GP says to do 999 if it happens and is uncontrolable. I have a phone by my bed which makes me feel safe during the night and in daytime I carry a mobile, it doesn't matter if you are unable to speak as your number is connected to emergency service and they would soon arrive to help. As Prem 51 said a personal alarm gives real assurance, all you have to do is press a button and somebody will help, I can really vouch for this idea, I used to work as an Emergency Response Warden and have reached people very quickly. I have never heard of a doctor saying this, when my hubby passed away I didn't like being alone but my doctor encouraged me, showed me what I could achieve. Now I love being on my own, I'm not answerable to anyone but myself, come and go as I wish, cook and eat when I want to and found lots of hobbies. By making myself independant I also became confident and my other condition is no longer a problem. As RRB said welcome each day and make the most of it enjoy your life and take doctors with a pinch of salt, they are not always right
