Is there anyone out there that can plz help me?

Because your 19 in high school. You feel different from everyone else and your friends outcast you because of it. You can't cry because you don't know what to think of it, whether you should feel sad or not. Age won't matter later in life, that's the good news. But you might have to try new things to get more friends. Try not to feel depressed about it, because life will get better. You should try and spend time with people that care about you. Focus on the good things in life. Best of wishes.
