Jack,
Remember the Five Stages of Grief as described to me during my therapy...
Denial: this helps us survive the loss. In this stage we are in a state of shock and denial. We go numb. It is nature's way of letting in only as much as we can handle.
Anger: is a necessary stage of the healing process. Be willing to feel your anger, even though it may seem endless. There are many other emotions under the anger and you will get to them in time. But anger is the emotion we are most used to managing. Underneath the anger is pain. Your pain.
Bargaining: Before the loss, you would have done anything if only the departed would be spared. After a loss, bargaining may take the form of a temporary truce.
Depression: After bargaining, our attention moves into the present. You will have empty feelings, grief enters your life on a deeper level, deeper than you ever imagined. This depressive stage feels as though it will last forever. But it's important to understand that this depressive state is not a sign of mental illness, it is the appropriate response to a great loss.
Acceptance: Acceptance is often confused with being "all right" or "Okay" with what has happened. This is not the case. Most people don't ever feel Okay about the loss. This stage is about accepting the reality that someone close to us is physically gone and recognizing that this new reality is a permanent reality.
Now enter PTSD. As a result of our trauma, pain, and training, we are stuck in "tough guy" mode, we are by-and-large numb, and tend to react to most stressful things with anger (meet aggression with aggression). When we were in the forces, we didn't have time to grieve. Not only that, it was a distraction that could get you killed as well... so we stuffed that shit waaay down deep. But, we never truly grieved the losses of those around us, or the loss of our former selves.
My therapist has been trying to get me grieve, and I try (when she makes me) and you know what happens? The memories come rushing in, the numbness leaves, and emotion comes on...and a single tear comes out of my eye. Then, something in me changes. I become cold and numb again and clamp down hard on all that shit....
She keeps telling me that a good cry, sobbing is how she puts it, will help tremendously. But I just can't do it...yet.
