Does everyone feel as alone as I do?

Because i think everyone on this planet feels alone. How tragic is that?! Billions of people on this earth can feel alone. Why? Well after i bring about world peace i'll get to work on that one. I graduated on saturday, and afterwards i've never wanted to cry more. My family has been through this three times before, so for them it was probably old news but for me it was the biggest deal! It hurt me so badly that my mom was just grumpy and my brother almost didn't make it. it hurts! why can't anyone see how bad it hurts?! Why is asking for help so hard? I just want to reach out and have someone look at me like i'm the most important thing in the world and say "i'm listening". someone that will be able to see what i'm going through and won't try to tell me what's happening when they don't have any idea! i just want to throw things and cry and scream because there's so much i want to do, so much i want to be and i'm afraid i won't do or be any of it. I'm scared. I'm lonely. I want my friends back, when they cared and when they were here for me. I didn't know it was going to be so hard to see my best friends go to college without me but the whole in my chest is getting to be unbearable. I can't take it anymore, all these things around me i feel are just closing in and i can't breathe. I just want to get away, be happy, and remember why i used to smile.
