Survivor (Cambridge Dictionaries)

Solution 2:

Any answer to this question must take note of the use of the word 'survivor' in circumstances which not long ago would have used the word 'victim'.

So, someone who had suffered sexual abuse in childhood might now in some cases be called a 'survivor' rather than a 'victim'. And when I say, '...might...', in politically correct language it is now '...must...'. If you have suffered abuse, then you are now a 'survivor'. It is not necessary for a 'survivor' in that sense to have faced literally life-threatening dangers.
