I feel your miserable pain. Just let yourself feel down sometimes. It's too hard to maintain cheerfulness when your legs are aching and you feel like you have been robbed of your healthy youth.
I coloured my hair when it was very short, and it made me feel more like myself. I know some people say not too, but what the hec, I did it anyway.
And you know what else, in just a few weeks ill be able to give you a great big hug in person......can't wait. In the meantime, cyber hugs and kisses
