This part really helped me:
Many a bad memory
Now drift on by.
I often think of what it will be like when I feel a lot better about things. I know I don't get to forget it all; I used to think I just want to forget all the crap, but now I'm not sure I want that anymore. What happened has had a big effect on me and I guess my attempts to cope with it all are shaping who I will be in coming years.
I like to think this means not that abuse shaped me, but that the challenge of dealing with it did. It will be okay if I can reach the point where I remember the bad things, but they just "drift on by".
Thanks for the thoughtful poem.
