To start off I have to say that I am sorry that you had to go through that. But you can't live your fears out through your daughters lives. I know it's hard to do but you have to try to let your daughters be free(not completely free but you know). If you haven't yet, I encourage you to tell your daughters what happened to you. I know you don't want them to think of you differently, but this will help them understand why you do some of the things you do. Keep your Faith in God. FAITH is the only thing that will get you through this hard time. My favorite verse in the bible is encouraging to me and was very encouraging to me when I was sexually abused. 1st Timothy 4:12 "Don't let anyone look down on you because you are young but set an example for the believers in speech, life, love, faith, and purity."
Sending bunches of hugs your way. and lots more love.
