Recently, I broke up with my girlfriend. Not that big of a deal, really. When we started dating, last year, we agreed that humans get together and separate easily. We've been together for over a year, and after a week of being single, I really miss her. Even tough I know I can find someone else, I want her. But I can't have her, so I just sit in the corner of my room listening to emo music and cry. I want this to stop, and the best place I can ask for help is here. Does anyone have something to make me fill even a little better?

This is a tough one. If I'm understanding correctly, you broke up with her, right? This implies that you were feeling doubts about your compatibility and the longevity of the relationship. In my personal experience, if you ever doubt that a person is right for you, they're not. My grandfather married my grandmother over 40 years ago and, to the day he died, never once doubted their relationship. That is what we should all strive for. If you did have doubt in your heart, it's best to move on. The right person will come along but it takes time. Either way, I know what you're feeling and I'm very sorry. I hope I've provided you some kind of comfort. Good luck, stay strong, and keep going.

That's it. I wasn't sure, so I just broke up. And then I started to think that it wasn't a very good idea. But you opened your eyes. Not that tough, actually. As in the title, just another teenager problem, and I feel kind of better now. Thank you!

Well a problem is a problem, big or small, and should never be dismissed if someone is struggling with it. While most teenage relationships don't last, it still sucks at the time. I'm just happy I could help a little.

I don't feel like I can add much to this, so unless you're bored, don't bother reading this.
But what you're feeling now is perfectly sensible. The human mind is incredibly stupid when it comes to longing for things it can't obtain. You are remembering the positive aspects because that way, the past will seem merrier, once you're over it, which happens with time and by talking about it, it'll become a positive memory that definitely influenced you in some way. Your relationship isn't lost, it has ended. The time you passed together is still there, the memories will remain and stay with you, even if you've grown apart, the time you spent was real. You are now yearning for things that have passed and can't be experienced anymore in the way they were before, but you'll certainly keep the memories which add to the person you are now. You'll grow stronger once you've overcome this phase.
