My sister moved back home a couple weeks ago. She's 24 and she wasn't making enough money where she was living before so my mom invited her home. Ever since she came home she has been someone I can't talk to about my parents. She has made me realize things I haven't before which make me realize how much I'm not seeing.

We would talk about my dad (her step dad) never treats her like a part of the family. I have noticed it too.

He treats her like a waste of space and money and can't seem to just peacefully co-exist with her around. He has a very bad temper. He resents her and takes the anger out on me or her. He causes bothersome of us a lot of anxiety.

She made me realize that out mom is just not supportive at all. She defends my dad before she defends us.

Anyway, I'm writing this because I'm upset, and mad, and I feel betrayed by my sister.

All those days we talked about how my mom doesn't defend us, I finally spoke up and when my mom asked what I was talking about, my sister defended her and acted like everything we talked about was just crap and ment nothing.

She was my support, and I feel like I lost that. I guess I'm looking for advice because being treated like the "little kid" just because in the youngest (I'm almost 16) makes me feel so useless and unwanted all the time...
