I am sorry for you loss. That must have been a very traumatic experience for you!

The symptoms that you described sounded more like generalized anxiety disorder to me. While the experience had to have been traumatic, your symptoms just don't sound like PTSD imo.

I do, myself, experience both PTSD and anxiety so I can relate to both disorders. PTSD, for me, is triggered by similar aspects of my trauma in the news or talking with those who played key roles in my life back then. Those times bring up a very intense anxiety inside of me. Flashbacks put me back into the terror. I have horrible nightmares that wake me, which rotate around people involved in my cause of distress. While I fight myself on avoidance, I do avoid triggers. Relationships with those involved in my life at that time, similar circumstances, watching or listening to current events, repression, etc. I am also very jumpy and anxious in general, for no particular reason. I startle very easily and visibly jump often. That is my personal experience. Below is a list of symptoms provided by NIMH for you to refer to.

What are the symptoms of PTSD?
PTSD can cause many symptoms. These symptoms can be grouped into three categories:
1. Re-experiencing symptoms:
Flashbacks—reliving the trauma over and over, including physical symptoms like a racing heart or sweating
Bad dreams
Frightening thoughts.
Re-experiencing symptoms may cause problems in a person’s everyday routine. They can start from the person’s own thoughts and feelings. Words, objects, or situations that are reminders of the event can also trigger re-experiencing.
2. Avoidance symptoms:
Staying away from places, events, or objects that are reminders of the experience
Feeling emotionally numb
Feeling strong guilt, depression, or worry
Losing interest in activities that were enjoyable in the past
Having trouble remembering the dangerous event.
Things that remind a person of the traumatic event can trigger avoidance symptoms. These symptoms may cause a person to change his or her personal routine. For example, after a bad car accident, a person who usually drives may avoid driving or riding in a car.
3. Hyperarousal symptoms:
Being easily startled
Feeling tense or “on edge”
Having difficulty sleeping, and/or having angry outbursts.
Hyperarousal symptoms are usually constant, instead of being triggered by things that remind one of the traumatic event. They can make the person feel stressed and angry. These symptoms may make it hard to do daily tasks, such as sleeping, eating, or concentrating.
It’s natural to have some of these symptoms after a dangerous event. Sometimes people have very serious symptoms that go away after a few weeks. This is called acute stress disorder, or ASD. When the symptoms last more than a few weeks and become an ongoing problem, they might be PTSD. Some people with PTSD don’t show any symptoms for weeks or months.

Very best wishes to you ~ take care!
