Hi TracyL and
I am sorry you had that happen to you - I was attacked at work too - are you seeing a psychologist or therapist? that is what has helped me the most to deal with the panic, nightmares and all the other parts of ptsd.
you wil find this a great place to come and ask questions and get and give support - hope things improve for your soon
take care P7
