Oblivious T.T

I'm so angry at everyone around me. I don't feel like I'm important in life. I just wish people would start listening to the quote, "Watch what you say, because that might be the last things you say to that person." I'm considering this quote and I think that it's really true. We should all watch what we say. People are so oblivious to when they hurt people's feelings in a simple joke. It may sound like a joke, but it can also deeply hurt someone. I literally have no one to trust now. All my friends don't see me as their best friend, mostly.
