Well, if we apply the estimate that at least one of six boys is abused by the time he is 18, then we are talking about at least three other classmates who may feel as you do but cannot speak out on their own behalf.
I can imagine how difficult the abuse scenes and the father's neglect would be for you, but at the same time I can also see how you would want to get through the book and overcome your feelings about it. One thing you might want to consider here is that when you say you would like to press on, are you stuffing back your feelings, like so many guys do at first, and telling yourself to "get over it"?
You begin here by saying:
This is a legitimate feeling, Chris!!
Its driving me crazy i have had the class twice this week.
i am quite confident that if i was at home alone like in my room with some privacy i could read the book alright... but in a class full of your peers its really hard...
You have every right to say to your teacher something like, "Sorry, I have tried to do this but this book is too close to home for me", and then ask for another assignment. You don't have to mention sexual abuse, and you don't even have to confirm that something happened to you personally. The problem would then be to find another assignment and an explanation for your absence or non-participation in the class.
I stress this because these days you are laying down the patterns and foundations you will be building on for your continuing work on your recovery in the future. It IS important for a guy to learn to ask for the help he needs and acknowledge and own his feelings. I know so often in my own past I refused to do either and all it got me was new pain and trauma. I thought to myself, well, that's what I deserve, that's what this stuff is like. Or else I figured I had to "be a man" and get on with things.
But it's not true, bro. We do have a right, just like everyone else, to seek a path through life that brings us contentment and peace as opposed to distress and turmoil.
As is so often the case in such things there's no easy way forward here. I just hope you will give this some honest thought and decide on the way that really works for you.
