Hi justej
I am the same age as you and have similar feelings I do use a barrier cream at times however following a strict hygeine routine link below helps a lot.
http://www.incontinentsupport.org/chap6.phpI have watched many prison films over the years and just like full strip searches for inmates. I have come to the conclusion that being incontinent is just the same however in diapers infront of medical people. I have resigned myself after initial shame and embarrisment to this fact and now sadly part of my life and just get on with it.
Diapers are the best thing to happen to me no fear of wet clothing, I now look at people of my age and say I can do what you do now. Diapers are a part of me now I feel bad when I have accidents though as I did the other week however the people here were great.
If your family love you they will understand and even supprise you with their reaction.
Take care you are not alone in what you are going through.
