Welcome Roger, so sorry to hear that you lost your leg, how on earth are you coping with it, it must be a terribly traumatic experience, do you get lots of support and an artificial limb? Have you checked out the really supportive forum that the famous Heather Mills-McCartney has set up? (I know that many people dont like her very much, but the forum is good).
I hope that things get better for you from now.
All the best
Karen
Challenges can be stumbling blocks or stepping stones, it depends how you view them
