Break Ups

Are relationships really that hard? I mean, right now I'm listening to my sister cry her eyes out because her boyfriend broke up with her and she doesn't know why. She's a mess right now. She won't stop crying and she hasn't eaten in a few days and she's locked herself in her room. I don't want to be mean, but she's being a little needy about this whole thing. She's trying to message him and trying to contact him and she shouldn't do that. But I guess that's what happens when you're in love, right? You feel like the whole world is nothing but a big ball of disappointment and nothing seems to go right. I feel like that all the time - just without the broken heart.
