We can tell that you have likely experienced trauma if your general sense of safety has been shaken, your sleep may be disrupted, and you may feel easily startled or jumpy at sudden noises. You may be checking your surroundings more than before and may have the ability to trust people if the trauma was caused by other humans. Trauma symptoms can be viewed in 3 large categories: anxiety, depression, and re-experiencing. Anxiety has to do with fear and nervousness, and often causes people to use avoidance as a way of managing it. Depression affects your mood, you may be irritable or angry, and see the world, yourself, or others more negatively than before. Re-experiencing includes nightmares and flashbacks.
