Welcome to WHL. You are definitely not the only teen member that we have. There is even a forum just for you guys. We older members love being cyber-aunties and uncles and we have cheered several young people on as they have finished high school and started college while dealing with AI diseases.
We're always glad to answer questions and to be a cheering support group, no matter what stage in life are members are going through.
I happen to be a retired high school teacher, and I miss my teenagers, so I'm always glad to be a cyber-auntie.
BTW - we have quite a few Aussies in our membership, too. So, read the stickys, read some established threads, and feel free to start new ones when you have questions. Since we have members all over the world, there is usually somebody hanging around who can answer your questions.
