Certain events in the past couple of months (namely breaking up with my long term gf, getting caught on LSD by my parents, rumors in school about me) may have changed me into a more cynical and bitter person.
Also some of my friends have called me out for being mean lately.
A factor could just be that I'm sometimes more introverted than other times, so that could be read as being mean.

I don't want to be cynical, but it's just too damn fun.
