Hi and welcome to TeenHelp!

Em has given you some great advice, and I agree with what she has said. It can be really unpleasant when people find out about what you're going through, but it is better that people are aware for your benefit. It seems as though your friend cares about you, and it's nice to know that you have a loyal person on your side during all of this. Like Em said, if you are confronted about it, I think it would be best for you to utilize the opportunity to get the help that you need. I had many opportunities years ago to seek help, but I rejected those and I regretted doing so later on.

If you're under eighteen, they're required by law to report it. However, this doesn't mean that they necessarily will. It all boils down to the individual that you're working with.

Like it was said above, you're definitely not obligated to show your scars. Do what you feel comfortable with; do what feels right to you.
