What is 'beautiful'?

To me, society/the media is telling us what is beautiful and what isn't. I thought that beauty in the inside, not how you look, but I guess people these days just don't agree. I don't like the way I look, and I have no confidence that nobody will never love me. Part of the reason of this is because society keeps telling us/me what 'beautiful' is. You have to be skinny to be beautiful, you have to be 'perfect'. I know not everybody thinks that, but most people do. I should love myself for who I am, but I just can't. Some models in those bulletin board ads are Photoshopped, even in magazines, and some people just don't know that. Some teen girls would die to look just like them, but in reality, that is unachievable, unless they get plastic surgery or something. My generation can be very judgmental. If you're not skinny, you're not pretty. People judge me, a lot. I've been compared to someone who wears tons of make up every day, and they say that she's the hotter version of me. We're only 13, and I barely know who this girl is. She's 13, and she wears so much make up, and believes that she doesn't look pretty without any. I know people who are underweight, and still say that they're fat. And they say it right in front of me, and sadly for me, I am overweight. To be honest, I don't understand my own generation.
     Most people act and talk like 'whores'. Some girls don't take relationships seriously. My generation can be ignorant, stupid, and heartless sometimes. And something that bothers me is that now people are replacing the word "sad" with "depressed". Sometimes I'll try to joke around to someone (who is relatively happy), not knowing that they're sad, and someone will go up to me and say "Hey! Leave him alone. He's depressed." I don't mean to be rude, but he's just sad, not depressed. Really, I've had friends that go through depression and it just gets annoying when people are replacing sad with depressed. Depression is a mental illness, sadness is just a feeling, don't get them mixed up.
      People don't look at your personality first. People judge you automatically by your looks and then try to get to know your personality. But the second they don't like your looks, they don't get to know you. That's just how reality is. What some people don't realize is that everyone they meet is afraid of something, loves something, and has lost something.
     This is what I hate about our society. To be so pressured to be perfect and then being surprised and disgusted when someone can’t cope with the expectations of this world. To look down on a person when they themselves hurt them so much that there is no other choice but take control in your own way.
     To the people who judge others and keep saying negative things to them. An actual person who literally slices themselves open on a daily basis just to get away from the emotional pain and come back to a physical state. I bet there’s someone you’ve said something rude to that went home and add a another scar to their already beautifully scarred skin. So yes in a literal sense you just made a mark in their life and you are now embedded into their skin forever. When I put it that way makes you think a little huh? It doesn’t take much to be friendly; no matter how much you can’t stand a person. Be kind. Because even though what you think is harmless could be the death of them.
