A little while ago, I did this journal thing you tagged me in. One of the questions was what character you remind me of, but I could never think of one. Well, I've thought of one now.
You remind me of James 'Jem' Carstairs from The Infernal Devices series by Cassandra Clare. Jem's always kind and happy, and his friends mean everything to him. And, despite his fatal illness, he gets on with his life and doesn't let it get him down.
I don't believe there's a character out there who could sum you up better.
