I too can relate. My mother was extremely uptight and anxious, and peppered me with warnings and horror stories about death and disfigurement. I think this has been passed down for many generations, because my grandmother who was generally a nice lady, routinely made me cry because I wasn't good enough or careful enough at specific tasks as a child.
While I don't believe that I was sexually abused, my mother led me to believe I was for many years, because she kept asking me questions like "did he ever touch you, are you sure he never touched you" after she left my father, and made comments like "I always knew there was something wrong the way he would walk around in his underwear when you were little" etc. As a child and young adult, I struggled with and fought these thoughts, alternating between thinking my father molested me and despising my mother for making me think it. I don't want to compare this to your experiences of abuse, I just thought I could relate on a certain level.
I have a good idea of the things we should avoid telling or burdening our kids with, as I too think often of how I must be sure not to pass this on to my kids the way my mom did to me. I've never really told anyone all the things my mother used to say to me, because I think they are embarrasing. But, here goes: don't strain on the toilet because you're cousin so-and-so died instantly from a blod clot in his brain when he did that; don't inhale a pea because it will sprout into your brain; don't sit on boy's laps because you will give them an erection (ok, this can happen, but hardly an appropriate thing to say to a teenaged girl!); if you don't dry between your toes after your bath you will grow fungus and mushrooms between them; etc etc etc.
Those are the extreme examples - it's not hard for me to avoid saying those kinds of things. But I do have to avoid the more subtle comments and actions - hovering is a bad one - making sure they don't spill, don't fall, don't make a mess (I remind myself daily to let my 2 year old BE a 2 year old, messes and all) but sometimes I slip.
I also am way too hard on my 12 year old step-son. He is so different from me. To me he is careless - to him he is carefree. And shouldn't he be? I was raised with so many rules of conduct and order,
