I can’t totally agree with “Paul met Debbies” statement. Because pushing and even crossing my boundaries has made me experience some of the most wonderful things in my life, like traveling off the track, dancing all night or skiping inhalation for a wonderful movie. But I am only talking for me here.
However, in the end it’s a question of finding the right balance between physical and psychological health. And in my opinion thats equally important. I do agree though that we have to listen to our bodies, in order to take responsibility for our decisions. You cannnot stay up all night, skip your treatment and then complain or selfpitty yourself. In that case you are nothing but a winy hypocrite.
Going back to your questions: I have experienced the biggest limitations after my 27th birthday, now I am 33. And its still a daily fight to accept what I was able to do and what I can’t do anymore.
What has really helped me was to ask for help. Very often my limitations occur when I am physically challenged, for example walking long distances, carrying luggage, having nothing to eat, and I mean immediately, not in half an hour or so. So I tell my strong and healthy friends to help out and support me in order to avoid physical exhaustion. But I am still in the beginning, because I tend to do everything by myself since I dont want to be a burden to anybody. Still I guess thats the best advice I can give to you.
