I can't take it..

I cry all the time. Today I could cry at the drop of the hat. There's many reasons to this:
1. I miss my best friend she is on the other side of the country and I can't see her everyday like I used to.
2. College. I know it's early.
3. Grades. It's crunch time and these next 2 weeks will either make or break my future.
4. People frankly bug me. Everyone is either being very negative about next school year or being conceded and obnoxious.
5. I need sleep!
6. I can literally not breathe until the last day of school and my last final is over.
7. I'm scared for summer. Last summer all I hung out was with my best friend Tyler, which isn't a bad thing don't get me wrong. But it's because no one invited me anywhere or asked to hang out or when I would try to get in touch with people, no one responded. And now Tyler is gone and only get to see her the couple weeks I go to Florida but there is still the rest of the summer where I could be lonely or have fun.
8. I'm scared for next year. Not because the seniors are gone it's because my grade and the future seniors don't believe in themselves enough. It's are time to step up and they need to stop dwelling in the past.
9. My appearance. I have broken out all over my face. I look disgusting.
10. The fact I'm even stressing in the first place.
