writing the things down may help - as Sannah suggested therapy can help you deal with the emotions and memories - accepting them and letting them go - thats hard - but a good T would help
In the meantime - relaxation techniques and if you have nightmares remind yourself that this is not happening now - its past and cant hurt you anymore - - distract your thoughts at these times if it gets to difficult - watch tv - read a boook - paint - write anything that distracts you
I hope you manage to get a T soon

When you have come to the edge of all light that you know and are about to drop off into the darkness of the unknown,
Faith is knowing One of two things will happen: There will be something solid to stand on or you will be taught to fly.
