Memories are just memories. Thoughts and feelings stuffed when they had to be stuffed to do the things you had to do in the abnormal situation you had to survive currently seeping into your consciousness bit by bit now that it is safe. Memories don't destroy you. Acting on the intrusive thoughts and feelings in your current situation, not managing your behavior while the intrusive thoughts and feelings pass is what destroys you. You will always have your memories, you will always have a flow of intrusive thoughts and feelings. The challenge ptsd brings us is learning to manage our current behavior in our current situation in a way that gets our current needs met while the intrusive thoughts and feelings are passing, sometimes raging in the background.
PTSD develops when a normal person is challenged with surviving an abnormal situation, is successful, then returns to a normal situation and suddenly all the ways of doing things and thinking about things they had to learn to survive are not only no longer needed, but are inappropriate.
Your therapist will be focused on helping you return to behaving appropriately in a normal situation, viewing the things you did in the process of surviving the abnormal situation as things the person caught in the abnormal situation felt they had to do to survive. It was the abnormal situation that generated the abnormal behavior. War is an abnormal situation. You're not at war now. A therapist can help you adjust to life after surviving the abnormal situation.
