I don't share too much personal stuff here or in real life. You're smart to do the same.
Most of us on here are using this site for therapeutic purposes, If some one is so bent on exposing me then I wouldn't care about them enough to worry.
I know what you mean and will sometimes ask people if they want to know my experience they need to message me then I can help.
I saw a man once ask for help with *********** on ep, if they see it, it's the internet and they may never know.
