@Former-Member I am going to repeat what I said to you last night - BRAVE and COURAGEOUS 
You have absolutely nothing to be ashamed about and you are NOT a disappointment. You are a remarkably resilient person and everything that happened to you was an absolute abuse of power and trust. NONE OF IT was your fault 
You were put in an incredibly difficult position by those who are supposed to care about you. The feelings you have are very natural - it is so hard to process the whys and hows at any stage of your life - but being so young makes it even harder.
I completely understand that feeling of a small part of you being destroyed every day - it is so very, very difficult.
@Former-Member This is what I have to say to YOU - you are here, you are talking, you are sharing, and you are strong!!!! I cannot say that it gets any better because I have not experienced that yet - but what I can say is that with support you will learn ways to deal with it better - and some days it really does seem like you are just 'existing, holding on and getting through'. These are the days that you reach out for support - if it is here that you feel most comfortable then there will always be someone to listen and to hold your hand until you come out the other side.
YOU ARE NOT ALONE - what happened to you should have NEVER happened but there is light at the end of the tunnel - it may be far away in the distance but it is still there!
Holding you up, walking beside you and listening when you want to talk.
