Possible origins:

I have been trough at least 3 traumatic experiences in my life:
My father's disease and death (15 years ago)
Witnessing domestic violence, threats of homicide and attempts of suicide (uncle/aunt) (10 years ago)
Have been beaten until uncounciousness by another uncle and psychologically abused for 2 years. (8 years ago)

Symptoms:
Difficulty falling asleep and trouble sleeping (when going trough the trauma I spent days without sleeping)
Insomnia
Anxiety
Sometimes I get hyperalert and defensive (like anyone could do me harm)
I frequently am reminded (by almost anything) of the traumatic events - not a day goes by that I am not reminded of an episode
Flashbacks
Relating my father's disease is like someone deleted that file in my mind - I can only remember little fragments
I have trouble managing my emotions, sometimes I outburst and I can be violent
I don't trust people
I feel the need to control my enviornment

My psychologist has not officially diagnosed me with anything (at least to my knowledge). I do agree that sometimes it is not needed to put a label on it, one just needs to solve it, of course, but reading about PTSD I identified with most of the symptoms, and so I'm asking: do I have PTSD?

thank you
