Avoidance: Avoiding certain people and places that remind the person of the experience.
Many people avoid talking about the trauma – and may distract themselves with work or hobbies.
Some people attempt to numb their emotions completely, which can lead to them becoming isolated and withdrawn.
Hyper-arousal: Leading to angry outbursts, irritability, insomnia and a lack of concentration.
Other mental health problems: Including depression, anxiety or phobias.
Self-harming or drug/alcohol misuse.
Physical symptoms: Headaches, dizziness, chest pains and tummy aches.
