I find that there are several things that can help. Firstly you have to put yourself and your needs first. Most of us spend our lives putting others first but I think you have to change when you become ill with a long term illness.You have to put your needs and yourself first. It may sound selfish but I think you have to put yourself first just to survive.I think you have to use your time to do the things that you enjoy and give you pleasure.You don`t have to do a lot physically just perhaps sitting on a beach looking out at a beautiful scene like that in the photograph can really lift your spirits. I also think its important that you try to keep occupied and busy as much as possible as this helps keep your mind off your troubles and stops you delving into self pity which I know from experience is so easy to do.It is also good to have a hobby that you enjoy and put a lot of your efforts into that. I research my family tree which is I find interesting and enjoyable and keeps my mind occupied. It is also a hobby that doesn`t take up much energy which is an important factor when you feel so tired all of the time.
The more positive you feel the more happier and contented you feel the better you will feel in yourself.Its amazing how much we can cope with and how easy it is to overcome even the biggest of obstacles when we are at peace with ourselves and our soul is happy and contented.
