Welcome. I know we have "spoken" in chat, but I just now read your introduction. As you have probably discovered, there are many roads that lead to and through MS. There are some truly heartbreaking stories out there.
I know one of the unspoken but cardinal rules seems to be that we don't judge or rank our CSA experiences. How can we? It's like saying scalding water hurts ME more than it hurts YOU. That's ridiculous and unproductive.
That said, I'm impressed that you told someone so early. I know you still carry the pain of CSA, but at least you were able to get your family in your corner early on. I wish I had done the same. I was such an independent kid...normally a good trait, but I used it to hide the CSA from my parents until just a few weeks ago---and im only a year older than you are. I think it was the combination of looking at 40, a new higher-pressure job, Sandusky, and the Boy Scout files that did it for me. There were numerous reasons I didn't tell before, but none of them were particularly good.
Like you, I'm an overachiever. I always looked and acted like a slacker kid, but one who always surprised others with what I was able to accomplish. I surprised myself. I did it mostly to forget or at least comparentalize what happened. It was quite a balancing act for years...a lot on my shoulders and Atlas finally shrugged and I told my wife, a T, and joined MS. I'm thankful I did. Just talking about it helps. I believe it was ChaseEric who said that talking about it removes its power. I find that to be true. As I always say...share as much or as little as you are comfortable with.
