... we are afraid of what others will think.
And afriad others will think we are copying.
Have had that problem the only other time we tried to actually say something out in a group..
Even the therapist of that group said "it's amazing how many people copy when the topic becomes this".. the therpist said it to the one who said we were copying. but we weren't! WE WERENT! we just keep it to ourselves.

Don't like being called a copy cat when we open up a big secret that took so much to even say.
(This happened back in 2009).
