I just really need to vent.

I'm so tired of being the one nobody likes. My own mother favors my sister over me. I ask to go do stuff with my mom, while my sister on the other hand tells her "I wish you were dead." Yet she takes her to do fun things. It's not fair. And I know life isn't fair. But it sucks that my own mother makes me feel so unwanted. I feel worthless. I just want to move out already, but I have 2 more years. I don't think I can take it for that much longer. I have 0 friends that I can talk to or hang out with. All I have is my boyfriend & he's always at work. I just need someone to want me around, & to actually show it. I try SO hard to get my mom's attention & it always ends bad on my end. I just want her to appreciate me & show me the affection I deserve.
