I've only told a few people. A couple of close friends, because I thought they deserved an explanation. A friend who is my "adopted brother", because I'm pretty sure he has combat related PTSD and he needs to get some help himself. I told him the unabridged version of "why I decided to see a therapist" hoping a light would go on in his stubborn head. (I guess it did, at least to a point.)
For the most part, I don't think it's anyone else's business. I don't really care how they choice to interpret it, but I know there can be a price to pay for giving them the information.
A few years ago, I had a good friend who was a teacher in a school for kids with problems. She's a cool lady and I'm sure she's well known as a "cool teacher". This was one of those friendships where you feel like you've known each other for years, the first time you meet. One day, she was talking about sexual abuse and how people who are abused go on to become child molesters. I was kind of appalled, but, she's a good and reasonable person, so I thought she'd benefit from learning that that stereotype isn't true. So, I said, "Although it's true that many abusers were also abused, MOST people who were abused don't go on to become abusers. I know that to be true not only from research, but because I was abused and I'd NEVER do anything like that to anyone else. I'd die before I'd let anyone hurt a kid."
You should have seen the expression on her face. The conversation died and so did the friendship. NOT something I expected! I would have expected it from some people, I sure didn't expect it from her. The only thing I can think is that she was THAT sure of her belief. Which is particularly tragic, because I'm sure a bunch of the kids she works with have been abused.
If you're going to share this kind of information, you'd best do it with your eyes wide open, because you don't always know what's going to happen next.
Personally, I HATE sympathy and not wanting THAT reaction from people is probably the main reason I don't say anything. It's kind of a "need to know" deal and most people don't need to know.
