Rape Poem

I was raped for 5 years by my grandfather from age 7 to 12 now I am 17 I have had courage to stand up to my mom and tell her I was leaving and also I have had the courage to turn my grandfather in for the rape and now I know that I drew strength from all the bad experiences that happened in the past and I think everyone can draw strength from their bad experiences

I have a big sister who is * years older than me. she went through a really rough patch when she was 18. she went off the deep end with drinking of hard liquor and parties galore. I just couldn't understand. a couple months ago I found out she had been raped those 4 years ago. and it explained sooo much. and now that I know what is bothering her and why she hates being hugged or showing her emotions. I don't know if I should tell her that I know or if it's better to not. I know that I can help her, but I.....don't know if its the right time to say anything, I just need some help.
