Location: Brisbane, Australia

Age: 18

Sex: Female

Drugs: No

Alcohol: No

Sports/ Activities: I used to do a lot of ballet and stage work, my ambition was to be a professional

dancer before I got sick. Nowadays I love to read, and other stuff like that, as well as spending a lot of

time with my family and friends.

Grades: I finished high school last year, and I haven't started college because I've been sick. But I got

subject prizes in three subjects and high as in the rest.

Favorite Subject: I loved Music, English, History and Biology. Hard to pick a favorite - they're all so

different.

Volunteer Work: It all depends on what you call "volunteer". Nothing really official, but I spend a lot of

my time working and playing with really sick kids, and they come to me for advice a lot.

What My Future Goals Are: I'd either like to go on to do stage work, or work with kids with serious

illnesses. I haven't decided which, yet.

What I do in My Spare Time: Talk to my friends and my family. Hang around with my hospital friends. Watch TV. Go to the movies when I can. I love going on picnics and other outdoorsy stuff.

How I'd Change the World: No question. Cure cancer. Eradicate it forever.

Largest Problem: Sometimes, I think it's having too many choices, and having too many expectations

and others having too many expectations of you. And all the implications (牵连) of this.

Why Would I Make a Good Counselor (顾问): I really want to help other people. I've made that my

life's ambition, to help as many people as I can.

Qualifications: I spend a lot of time doing this sort of stuff "unofficially" - I am the Discussion Manager
