ElizabethHello!
You may want to contact Kelly Leight at the Cares Foundation. She has a huge base of people around the US that have contacted her - and I thought at one point she mentioned putting together a penpal group but I"m not sure.
You or your parents can reach her at Kelly@caresfoundation.org she is very nice and a great source of info.
I’m so glad you are looking for someone! I would put you in touch with my daughter but she hasn’t reached her first birthday yet ;-)
Good luck!
