Why do my mom have to over-react to everything?

Everyone's moms suck sometimes, but my best advice to you is to not post things on the internet when you're still pissed. Trust me, I've done it and it really only makes things worse! Your mom is probably just thinking about what's best for everyone and is focused on the well being of the kid, I mean, he is only 7. As for the lights, it's good to cut back on things to save money these days. It's okay if you don't always get along with your mom, but just realize that she does love you even though sometimes it might be hard to see.
