I can only suggest that if you are being treated by a psychiatrist, move to a psychologist.
Psychiatrists believe in healing through medication...and all of them have bad side-effects.
Psychologists, may prescribe some medication, but their main preference is the healing of the mind through their guidance and you learning how to face the past and let it go.
There is so much that is good about life, it really is terrible that you are not free to live it as you should. A crime or series of crimes were perpetrated against you; do not allow that your own mind and nightmares do the same. Aim for wherever your minds eye sees sunlight and healing...and even laughter and love, because what you may think, you do deserve it.
