Your friends and family care about you. I know mine do! So, as you go through this, they are going to want information right from the start or decide when you should tell what happened.
This happened to me. From what I have read from other blogs and heard from other people who have gone through similiar things, you will end up being probed for information sooner or later. It is only a matter of time. You are loved so much by these people and it scares them not to know what happened. It is human nature to automatically think the worst. They are worried and scared for you and your safety.
You need to understand something though - you need to tell who you feel you need or want to tell what happened. As much as you may love these people back, you are not helping anyone by pushing yourself to tell when you are not emotionally ready. If anything, I found that this may cause you to start to hide from people. You may start to hide information, emotions, and anything else that may be of use to get out in the open.
Your family and friends love you, but don't do anything you aren't ready to do!
