PTSD has five stages, including:
Emergency Stage - during this stage, your anxiety levels may be extremely high, and you may find yourself having an intense reaction to everything. This is because your body's flight or flight system is kicking in.
The Numbing Stage - during this stage, your body is trying to instinctively protect you from more emotional distress. You may feel like your emotions are totally shut off, making it difficult to deal with the trauma you experienced.
The Intrusive Repetitive Stage - during this stage, you may try to process your emotions, but will often experience flashbacks, nightmares, and anxiety. For some, this is the most damaging stage of the illness, but recovery is possible.
The Transition Stage - during this stage, you will begin your PTSD recovery journey. You will learn to understand and accept the trauma that happened to you, and start to heal.
The Integration Stage - during this stage, you'll work through your recovery and learn to integrate your new coping skills into your daily life, so you can deal with any remaining symptoms as they arise.
