One of Those Days

Have you ever had one of those days where everything just annoys you? I seem to have that at least twice a week. I'm an inteliigent person, and I usually like to help people when they have questions in class. But sometimes I feel like they're just using me for what I know and not caring about who I am. It's these days that I'm the most introverted and tend to snap at anyone/everyone that asks for help, which goes against the message that I usually try to send, that I'm here to help. It's days like these that I just need to take a breath and be by myself for a while, but the thing is, I hate being by myself so much. In fact, it's because I'm so alone that I have so many of these days.
I guess I just hate living in my town/state. I've lived here all my life and nothing's really been any different. I've never really met anyone that's enough like me where we can share opinions and not hate each other.
I don't know. This is just a rambling. I'm just upset is all.
