Sometimes I talk about people behind their back (not in a malicious way just for eg if a friend has upset me)
We all do this, don't sweat it. everyone needs a second opinion or someone to talk to about things that have upset you
I am also shy but put on a big front to cover it (like many people I guess) and over analyse my actions to the point of being self obsessed.
I always over analyse what I say and do to the extreme. I didn't say thank you to the Ticket Inspector when I got off the train today and I felt bad about it all the way home right up until I banged my knee on a cupboard in the kitchen. Like you I am very shy and I sometimes use alcohol to bring me out of my shell, then the next day I hate the 'out-of-shell' me. I can't win
I try so hard to be liked and make people like me that I think I drive people away by doing this. I hate myself so much, I want to die (I wouldn't do anything I don't think but the anxiety etc is crippling sometimes)
Everyone does this as well, but most people don't have the strength of character you do to recognise this. Having self-awareness is what makes us nice people to be around. Nobody hates anyone for trying to be liked.
Sorry here I go again I know there's more important problems in the world and this is extremely minor and trivial. I just feel sick I really want people to like me, it means so much and it shouldn't
below is a quote that helps me out when I'm recovering from hangover induced fear...
"You’ll Worry Less About What People Think of You When You Realize How Seldom They Do"
