Ill health can make you feel down, your own limits of what you can do, and others give you the problem of trying to help them enjoy life the best they can.
The best course of action. so that it does not get you down is to take a positive attitude and compare it with a worse situation, but also to see other positives, like you get so spend more time together or get time to read a book you always wanted to or to take up a new hobby.
Illness that limits what you can do for an extended time or forces you to change your life style are the most annoying, but they also give you the opportunity to sit down and force you to carry out a life audit, and sort out what you are going to do from here. So although restricting may open up an exciting new direction, or interest.
As to others ill health, the one piece of advice we would give is to be completely honest with them, don't say they are going to get better if they are not, or that you are going to do something with them next year if you have been told they have only got a few months left. Most people face death far better than those around them and are just glad they had the time to put their affairs straight, and sort out their lives. If you know they have a limited amount of time left, don't get all weepy, or annoyed, but instead help them to live it up and enjoy the remaining time to the full.
As life is terminal for us all, perhaps we should all be enjoying life to the full now.
