When you are given a diagnosis of PTSD, you might be told that you have different levels, like severe, moderate or mild PTSD. 

Look at this as what sort of impact your symptoms are having on you in the present – it's not a description of how upsetting or frightening your experiences were.

Common signs and symptoms that you might recognise, but everyone's experience is different, so it's possible you may experience all, some or none of these things.

Flashbacks, nightmares, feeling it's happening now and intense distress at reminders of the trauma, to list some.
