To ask what make one become a likely bullying victim?

[AuntyLily]

I'm in my 40s and have been bullied in every workplace except one. I'm trying to work through these issues so what makes a person more susceptible to bullying in your opinion?

I have been picked on quite a lot in life and what has made a difference to me is to not let them show that it bothers you. If you laugh and brush it off they won't get such a kick out of it.
