You don't 'just get over it' without a lot of help and support. I was taught to 'be a man', 'be strong', 'don't show your emotions', 'don't be a baby'. It's all BS, real men do get emotional, cry and seek help when they need it. Hell, I'll even look at maps and ask for directions. Healing is something that I couldn't have done alone. This is a good place to start. I envy the fact that you're dealing with this now at your age. I'm an older guy who waited 38 years before I told anyone about being abused and by then I still wasn't 'over it'.
Take good care of yourself, look at all the resources that are available here on the site and check out what's available in your immediate area. You're not alone here, this is a very supportive place to be.
I want to stay as close to the edge as I can without going over. Out on the edge you see all kinds of things you can't see from the center.
