PTSD symptoms can develop instantly or may develop over a few minutes, day, months or even years.
Flashbacks. Vivid memories of the situation playing out and feeling as though it’s happening right now, resulting in intense feelings which you experienced in the past.
Avoidance. The feelings and memories are so intense; you struggle to deal with them so you block them, allowing you to cope on a day-to-day basis.
Guarded. You become more guarded, feeling tense and waiting in anticipation for when something might trigger you, you’re always on your guard.
