There is a direct link between our mind and our immune system. Do all you can to stay positive, never give up hope and never lose faith in the future. If you have a reason for existing then you will have the ability to endure anything life throws at you. If you are down or confused, feel lost or unappreciated then search deep and uncover that reason for you to exist. Woe to those who saw no more sense in their lives, no aim, no purpose and therefore no point in carrying on.You are loved, you are important and you are needed. I may not know you but I would be happy to call you my friend. Life is absolutely amazing. Believe in yourself like I believe in you.
