i feel so bad for you over what happened to you as a boy. i too was 5 when it started - but it was a step-dad - not a real father. i would think that what you endured would even be worse. the shame you feel is natural - but it is a result of what was done to you - not your choice or fault.
i am glad you have found us and decided to speak out. i hope you will find comfort, support and encouragement here among others who have had similar experiences and can relate to what you feel.
We are often troubled, but not crushed;
sometimes in doubt, but never in despair;
there are many enemies, but we are never without a friend;
and though badly hurt at times, we are not destroyed.
- Paul, II Cor 4:8-9
