feeling confused and uneasy about a decision

So I just read on the news that there is a local 1 year old girl that needs a bone marrow transplant. They are doing drives to find a possible match. I think I want to go and I think I want to be a match. But I am so scared to have the transplant. Not to mention the procedure is taking place in Toronto, which would mean I would have to get on a plane which also scares the crap out of me. I wish I could think of someone other than myself. I wish I could just get over these fears and actually do something valuable with my life.
