The LAN feeling hopeless. surprised?

You guys, I feel so hopeless sometimes. I feel like I'm the type of person that will say the wrong things 99.9% of the time. I'm so tired of everything. School is biting me in the ass. And my boyfriend isn't making it any better. Sometimes, I feel as if he doesn't understand where I'm coming from. Sometimes, I take things too lightly or say the wrong things. I can't help it. That's how I am. But he always expects me to be perfect. I cannot do that. Don't get me wrong. I love this kid so much. I love him so so much. But he'll never understand. I don't think a person can understand how much you love them because you're not them. It's frustrating. And I PMS. I'm a fucking girl. I have my weeks. For example, you guys know that I'm a private person. I don't talk about it a lot because that's not how I am. He just assumes that I never understand anything. But when HE'S the one that NEVER understands me. Even if he tried. But you guys, I don't know why. I love him so much. He doesn't treat me badly. I do say the wrong things a lot. And i'm too irrational. I don't know. With this. And school. I don't know what to do anymore.
