Stuck in the Middle

I was born between my sister and my brother. My brother is the oldest, 15 years old. My sister is the youngest, 12 years old. So, that leaves me to be stuck in the middle at 13 years old. I hate being the middle child. My sister gets whatever she wants. I call her "Mommy's Little Devil" and so does my brother. My brother doesn't get as much as her, but still gets much more than me. I am always treated like crap. Sometimes my mom gives my sister and brother allowance, but gives me nothing because she supposedly "ran out of money." Ran out of money, my butt! She is just lying because she don't give a crap about me. Me being the middle child is probably the main reason I have to deal with depression. I always feel like I'm being left out. I don't see how the kids at school like me. I'm even surprised I have a girlfriend! I just hate being the middle child. That's all there is to it.
