Never shut off pain till it eats you up completely. Ensure you find someone you can confide in and trust, share your burdens, cry if you need to by letting it all out. No one is conditioned for pain. We all need to address it and let it go, knowing we cannot change the past but we can make a brighter future out of the lessons learned.
I'm just not going to do it so that we can say that we've done it. And I'm not going to do it if the first thing you say afterwards is 'please don't tell anyone' or 'let's forget it ever happened'. If you have to keep something secret it's because you shouldn't be doing it in the first place!
