Tomorrow my marching band goes to an elementary school to perform and we have to wear our summer uniforms, which are short sleeved polos with the logo embroided on the chest. I'm so scared because I've been self harming every day this week so all of the scars on my arms are new and Idk if I can use makeup on them yet. When we're performing I probably won't be able to wear a jacket which is really scary. I don't want anybody to see them because I have a good standing with the band and I'm in line to be section leader and I don't want anyone's perspective of me to be changed, especially kids that I've known and am friends with, as well as the first year marchers who look up to me. Only one person knows about it and I want to keep it that way. I'm panicking! What can I do?
