Nervous about using my crutches?

I'm 14 and yesterday while playing basketball w/my brother I hurt my ankle. Its a hairline fracture and I have to wear a cast. I'm in a temporary cast right now and I'm getting a real cast on friday. I think I'll get pink or light blue because I love those colors and I can see what people write on it. I can use a wheelchair but I would rather use crutches because it will attract less attention, I mean lots of people at my school are on crutches every day. I'm afraid that I'll fall, or I won't get to class on time or I'll rin into people in the hall. I've had a cast on my arm before but It was during the summer so I wasn't in school. You don't think that It will hurt when they put the cast on or when its on do you. Can I wear a sock over the cast I think I'll have a shoe that goes over the cast

I've played w/crutches but I've never actually had to use them, and they hurt your arms is there anything I can do to help with that

It is not hard to walk on crutches but you will need to practice. If the crutches are properly fitted they will not hurt your arms. There is supposed to be two fingers space between the underarm and the top of the crutch under your arm. The hand bars are supposed to be seated so that your arm is not fully extended when you put your weight on them. The crutches move a bit forward and then you swing your good leg and the bad one to meet them.
