I am altruistic. I was thinking today that I do actually try to give to others, and to try and help those in pain or suffering. 
I give the photos I take of runners freely. Today one was published in a newspaper, and they have been used freely for the running clubs publicity
In my blog I offer help and enocuragement to those suffering knee pain like I did for many years. 
I raise money for charities. 
I donate to nature conservancies. 
I try to encourage and inpsire through my running endeavours
Basically I am a good person, and I don't deserve the names I get called because of my anxiety. 
My altruism stems from a need to do good things, to lift my low self esteem.
