Thanks for the warning Gambot. I think that men, more than woman don't realise stress when they are suffering it. I remember my dentist telling me I was stressed, I laughed, until he pointed out the grinding of my teeth in my sleep!!!!
Not nearly as serious as your story but highlights how stress can be affecting us without us knowing it.
Great advice about letting go, taking time out and treating ourselves to some me time. As others have said talking too helps. Sometimes a post on here can relieve a lot of stress and long may it last.
Look after yourself and hopefully your warning is the last you will hear about it for a fair few decades at least.
