I frequently use multiple different personas online
Why do you use different online personas?
I like keeping my real life private.
I know it can be tempting to do this but you should not pretend to be someone you are not. Life is more fulfilling if you try to be yourself.
We are all different and feel different things, who are you to say I can't do this or that.
Well if you are honest with people they might still find you interesting. You don't need to make up so much stuff because you could forget and mix up the stories.
