I don't know that more ailments make us older, but it does make us wiser to the ways of the world and more compassionate to ourselves and the struggles of others. It is not easy to struggle with ailments and illness. You might be surprised as to how many others are in the same boat that at such young ages, and even younger let alone older, are dealing with quite a umber of ailments and illnesses. It does not make it any less troublesome though to have to deal with the illnesses but know that we may not realize what others go through, everyone has something they have to contend with, that we are not alone. We just have to try to take in stride what we are faced with, do what we can to take the best care of ourselves, get the treatment that we need, do what we need to to get through each day, and know we are not alone, never alone. It may not make us old, but it definitely brings out our strength, our courage, and makes us survivors.
I hope you find some peace and good care to help you with all that you are contending with. Hang in there meanwhile. Wishing you well.
