A Stressful Time

So around this time, every high school senior in the country is or should be freaking out. College is coming up, school is becoming vigorous (especially for those of us taking AP courses), and this is all while trying to balance spare time with friends, family, working, sports, and by oneself. However life has been particularly stressful for me the past week....
First of all, one of my good friends Nils had another party. This time his mom found out about it. What luck?!?!? So his basement is officially and forever closed. Oh well we had a good run. In addition, she decided to call my mother. Fortunately, I had been honest with my mom so she was not mad, but still it felt like I had betrayed the two of them and lost their trust. Now at this party, Christina came. She like everyone else slept there. However, she lied to her parents and when they found out, it was not pretty. She is currently grounded for eternity and the next time I go over her house, her dad wants to have a little "chat". This is the same dad who has the gun.
The next day, she and I were texting and she asked how many girls I had slept with. I answered honestly, 1. I then asked her the same thing. Her response: 3. I was extremely frustrated by this because she has accused me of being a player since we first started talking. Little did I know she was a player to the MAX. She then went on to tell me that she had cheated on her last boyfriend!! How am I supposed to realistically trust a girl who admits something like that. Even worse was the fact that the day before she had gotten my permission to go to a laungiere party with her friends. Now how am I supposed to take my permission back? Its frustrating.
This is not even the worst part. All of my friends have all but stopped talking to me, and none of them will tell me why. And they all are denying it, but I can tell when they are pissed and they are. Sometimes I just wish high school was over... Oh wait, it almost is.
