welcome to pip...
I'm sorry to hear what your dad did...
this is painful to read...
I would say some things to make you feel better, but I know they are just words and won't heal your hurt as I wish them to.
expressing yourself through poetry is a good start, no matter how you write...
it's good that you are letting it out in a positive manner. Please know that there are people here who have been through similar things, and we do care.
Keep spilling it on paper, let your emotions out...
