Welcome to adolesence. And I mean that in the most non-mocking way possible. Life starts getting tough in your teenage years. Mine did, my friends' did, and though I doubt they will admit it, I'm absolutely certain that everyone here has felt like you do right now at least once, be it over a member of the opposite (or same) sex, a friend, a family member, whatever. The important part is for you to not feel alone. As you said, this place is a big part of your life. Well you're a big part of this place too.

Even at age 19, I've felt like you're describing recently. My ex-girlfriend broke up with me in the worst way possible (pm me if you want the whole story). But I got through it by talking to my friends about it, and listening to what they had to say. No matter what happens, you'll always have friends by your side. It's the one constant in life, it would appear. If you think of these problems as little wars that you have to fight, than a quote comes to mind from the lips of Tupac himself that should fit this situation perfectly: "Wars come and go, but my soldiers stay eternal"

You'll get through this, and you'll get through the next set of troubles too. And when you finally make it out the other side into adulthood, you'll look back and smile, knowing that while they had their ups and downs, these will be some of the best years of your life.
