Can anyone help me?

Every week we have P.E at school, no biggie right? No, the thing is that I cut severely on my lower arm/wrists, and I have to get changed in front of people, and I HAVE to wear short sleeve. If anyone can help me in figuring out how to stop, or cover the scars and fresh wounds, I am open to ideas. The whole reason behind this post, really, was to stop my few friends from finding out about them. As said before, tips/tricks will be considered as I really don't want to hurt them.

ALUMINA

Alumina is a free, online 7 week course for young people struggling with self-harm. Each course has up to 8 young people, all accessing the sessions from their own phones, tablets or laptops across the UK. The courses take place on different evenings of the week and are run by friendly, trained counsellors and volunteer youth workers. You don’t need an adult to refer you or sign you up, and no-one will see or hear you during the sessions – you’ll just join in via the chatbox. We want to help you to find your next steps towards recovery, wherever you are on your journey.
