I know that change is possible because I wasn't always like this. I just got angrier and angrier and more pissed off at everything and anything throughout my teens. 10-year-old me would be mortified at what she's turned into.
I'm in my late 20s and a generally unpleasant person. When I'm away from whatever/whoever is annoying me, I kick myself for how I behave, I don't even care about 99.9% of the things that annoy me, I resolve to be better, and then I slip straight back into being awful.
I've been thinking about counselling. I've had a relatively straight-forward life but I've never talked about being picked on at school to anybody. It seems daft to try to blame my crappy behaviour on people being crappy to me 15 years ago but that's when it started so I wonder if acknowledging it might help.
Has anybody managed to drastically turn themselves around with counselling or some other way?
