Being a witness survivor can be extremely traumatic and it is likely that what you are feeling is normal. You may have had some of the reactions below. You may not, that is also completely normal because everyone reacts differently.
Panic and anxiety
You might also find you are:
avoiding the place where you witnessed the suicide
feeling anxious and panicky when you have to go near that place
not sleeping well, and/or you have disturbing dreams and nightmares
having disturbing thoughts you can’t block out
thinking about death and dying
feeling generally anxious
wanting to be alone
avoiding social situations
losing track of time
more impulsive and reckless in your behaviour
using alcohol or drugs more than usual
You may find that you react over time and that your thoughts and feelings change. This is a completely normal reaction to trauma. If you know other witness survivors, you may find you are reacting differently. Again, this is normal as people deal with trauma in different ways.
