I dont really know where to start, firstly i think its very brave to write this and get it out.
it was very well written with you describing it very powerfully and with each line and sentence it gave out the powerful pain of what the poem was about.
using mummy and daddy through out the poem only added to this pain as its just something that shuold never be used in the way it is in your writing.
the words that remain with you are not true. not at all. i know its hard to believe but you are worth a lot. and i can understand why you would feel dead inside after all this, but you have a life and you deserve happiness and to live your life.
