Thank you both.
I was very hesitant about describing myself as an empath because of the 'modern' 'fashionable' 'buzz word' aspect.
I don't usually have much of a problem with reflecting or imitating or just 'feeling' the moods, worries, feelings of others though it is fairly often that I have an insight into something or someone that I am pretty sure I haven't been told. I have to really think things through to work out whether I am projecting or whether I actually am sensing something.
This 'my body is giving me physical reactions to someone else's stress' is not pleasant though ... and
