I agree that you should be evaluated.But while waiting or deciding to do that,here's a little info:

DSM-5 Criteria for PTSD

(1). All of the criteria are required for the diagnosis of PTSD. The following text summarizes the diagnostic criteria:

Criterion A (one required): The person was exposed to: death, threatened death, actual or threatened serious injury, or actual or threatened sexual violence, in the following way(s):
Direct exposure
Witnessing the trauma
Learning that a relative or close friend was exposed to a trauma
Indirect exposure to aversive details of the trauma, usually in the course of professional duties (e.g., first responders, medics)

Criterion B (one required): The traumatic event is persistently re-experienced, in the following way(s):
Intrusive thoughts
Nightmares
Flashbacks
Emotional distress after exposure to traumatic reminders
Physical reactivity after exposure to traumatic reminders

Criterion C (one required): Avoidance of trauma-related stimuli after the trauma, in the following way(s):
Trauma-related thoughts or feelings
Trauma-related reminders
Criterion D (two required): Negative thoughts or feelings that began or worsened after the trauma, in the following way(s):
Inability to recall key features of the trauma
Overly negative thoughts and assumptions about oneself or the world
Exaggerated blame of self or others for causing the trauma
Negative affect
Decreased interest in activities
Feeling isolated
Difficulty experiencing positive affect

Criterion E (two required): Trauma-related arousal and reactivity that began or worsened after the trauma, in the following way(s):
Irritability or aggression
Risky or destructive behavior
Hypervigilance
Heightened startle reaction
Difficulty concentrating
Difficulty sleeping

Criterion F (required): Symptoms last for more than 1 month.

Criterion G (required): Symptoms create distress or functional impairment (e.g., social, occupational).

Criterion H (required): Symptoms are not due to medication, substance use, or other illness

Two specifications:
Dissociative Specification. In addition to meeting criteria for diagnosis, an individual experiences high levels of either of the following in reaction to trauma-related stimuli:

Depersonalization. Experience of being an outside observer of or detached from oneself (e.g., feeling as if "this is not happening to me" or one were in a dream).

Derealization. Experience of unreality, distance, or distortion (e.g., "things are not real").
Delayed Specification. Full diagnostic criteria are not met until at least six months after the trauma(s), although onset of symptoms may occur immediately.
