Nobody is willing to love me...?

So I'm 14, guy, hanging out with my 2 other friends, same age. Today, we went over to my friend Stephanie's house, and went to a dam to hang out. We were in the dried out water passage sitting down lightin a few bowls. So it was me, my friends Zach, Calvin, Jeanette, and Stephanie. I didn't know that my friend Calvin had a crush on Jeanette, but I knew Zach and Stephanie liked eachother, so I figured that since me, Jeanette and Calvin were just friends, nothing would happen. Well, we were sitting in the water passage, and Zach and Stephanie just start making out. We throw a condom on Zach as a joke and climb up out of the platform, so we're right over them. When I'm looking away for a minute, Jeanette and Calvin just start making out. So I'm the only one left, with no one to do anything with. Now they're all dating one another. After this day, I am still the only one who left heartbroken and alone. When we were waiting for our ride at Stephanie's house, I was sitting on my bike, and I look over and the Zach and Stephanie are making out, and Calvin and Jeanette start to do the same. So I'm sitting their, alone again, and I felt like my heart was being torn out of my chest and just destroyed. I wanted to cry so bad, but I didn't. So I was pretty much depressed for the whole time after. When everyone finishes making out, they look over at me and everyone says something to make me feel better about being alone or to just tease me. Also, I have never had a girlfriend and I have never kissed a girl. At this point, I'm ready to just go back to that dam and drown myself. I hate myself, and my life. I've been alone forever, and that's how it's going to always be, because no one could ever love me. Someone, just please kill me. I don't care how, I just want to get out of this sh*tty life.
