She Made Me Suffer Even Lower Self Esteem..

Recently I went to one of the depression support groups & I saw this lady sitting by herself.  She looked liked she was alone with no one to talk to, so I went over to have a chat with her.  When I approached her, she chased me away.  She said she didn't want to talk, so I backed off.  The next thing she did was she went over and told this other person in a meeting how I approached her.  I was very much hurt.. I was trying to be nice and she had to pull something like that.. I told her off aftwards because what she did was totally wrong..  She didn't want to talk to me is one thing, but talking about me to someone else is very much out of line!  Still I was hurt, so I never went back to that meeting.  How can people be THAT cruel..  Since then I've developed more low self esteem.  Now I'm afraid to go up and talk to people after that experience..
