Heartbreaking to hear your stories... My heart goes out to you....

You know you have PTSD when:

You don't trust anyone.
You have lost all faith in humanity.
You begin to see life as a means about survival; the world is dark and scary.
You spend years of your life "coping."
You have isolated from everyone and everything.
You have so many triggers you end up doing nothing but sitting in negativity.
You shut the door on friends and family.
You cannot discern whether you are in real danger in the present moment because in the past you were in danger.
You want so badly to trust someone but everyone seems to fail.
You are SO sensitive, everything hurts.
You can go from zero to a hundred in terms of anger.
When someone hurts you, you are easily re-traumatized.
You resort to age-regression as a means of coping.
Somatic suffering and pain.
Hyper vigilance and fight / flight mode that you cannot seem to disable.
Rarely ever have a relaxing moment.
Endless endless endless ruminations.

Among many many more things.
