The best defense for people who are shunned is to really start
working on creating community in your life. Be where people are.
Do the things you enjoy in groups. There are so many positive groups
you can get involved in. If you are at a loss start with meetups
http://www.meetup.com there are groups for all reasons, just go and
socialize and be hospitable with neighbors and good people you find
along the way, re-create yourself, don't just sit there, isolated and feeling
blue and alone, there are always other people out there who would enjoy
you company. You can meet people in groups that; hike, bike, like computers,
do art projects, sewing groups, travel groups, business start up groups,
have brunch together, writing , "Just Write"is one , there's a group
called 'Drinkers with a Cycling Problem', and Kayakers and paddlers of Dragon Boats,
So don't your past bad treatment at the hands of others, define your life.
