extremely exhausted..

I'm tired of keeping my cool for those who don't deserve it. It's more than extremely hard for me to keep myself sane when all else is driving me to insanity. Let's begin with my heartbreaker.
      Suddenly he messaged me on facebook and said all the sorries and lets remain friends crap. It made me sad for days from hearing from him again. For some reason it still stings..a lot. I literally felt like he was reopening all of my wounds. I replied and responded to him but I will never let him back in my life to hurt me again.
     Next big thing is my trip to PCB. Honestly, I was sad/irritated most of the time we were on the trip. My friends kept getting mad at the little stuff. Whenever I open my mouth they seemed to get piss. So when I kept my mouth shut they assumed I was pissed off. My friend CL kept having this mad face on and my friend TL was being a total bitch. For the first time in my life, I wanted to go home while on a trip. I didn't feel like I belonged and I was too fed up with their shit. When we came back to work, they told everyone about the trip and made me the "problem". I'm furious right now. If theh have a problem with me then they need to tell me before blabbing bullshit out of their mouths. What got me really mad is that they told my sister and she was on to me. From the way she was talking, it didn't matter if I explained my story to her anyway. She started off with an accusation that eveything is my fault..i'm so angry.
