why

So why cant the past leave me alone????? I woke up from a nightmare in a full blown panic attack today.
The nightmare was about the past of course and it had all the people in it that I want to erase from my mind... It had everything... people chasing me, trying to hurt me, forcing me out of a job, not believing what I had to say, violence etc.
Yesterday Ash scolded me for being aggressive... what else am I supposed to do? I told her that is why I am on meds and she is not.
Past GO AWAY... I don't want you here anymore. You have done enough damage to me and cost me everything.... GO AWAY.
