Trying to live,
My situation was exactly like yours. My brother abused me when I was 11-15. Congratulations on getting up the courage to speak for the first time, and you could not have picked a better place to do it. Here you are welcome, cared for and listened to. Do what feels right, post more of your story, just read the great advice of the others, or PM any one of the great guys here who you seem to resonate with. Whatever you need at the beginning of your journey, we are here to help!
