It is a shame to let the fear of illness ruin your life. My dad died of a heart attack when i was 22 and my mum died of cancer when I was 35, so there is real risk if either illness in our family. But until you are told you have it, I think you have to try and live as full a life as possible. I never know when depression is round the corner because of hormone imbalances for various reasons, but after I get over each lot, I try to go back to living a full life, even if a bit different.
