People are going to say things that are meant to put you down. twist your life, and sometimes turn it to hell. People can be immature and think that you will fall. There's only one reason that they could do this. One reason in total, when zeroing out all the other options, and that is the fault of one individual thing. I blame it all on stupidity.
People are going to make comments that are intentionally to make you upset, but it is how you decipher it. If you decipher it as a joke, then it won't hurt as bad. It will make you angry, but don't let it. Some people are taken over by stupidity.
