I Have Done Things I Am Not Proud of

@Mr well people in real life don't hate me, I'm very polite and usually quiet so they have no reason to but people on the Internet do because I'm honest and I don't like to sugarcoat things. Some people are accustomed to being around fake individuals who never tell the truth to their face (but will talk behind their backs) but I'm not like that. Another thing is that I tend to be pessimistic because the fact that we, humans are ruining everything around us, and that is causing a great pain because I get affected by things that don't directly influence me. This often causes me to be bitter and people to think that I am insensitive when in fact I'm hurting. I'm not sure if this makes any sense and if you understand what I mean.
