I need some serious help. Here’s my story, and please comment to help if you can. I’m still new.

So, of course, like many of us did, my younger sister was afraid to sleep on her own, even if I was in the same room as her. So, my older sister and I slept with her for a LONG time, and then when she became used to it, we stopped. So my younger sister and I share a room with my two stepbrothers who come every other weekend. Okay, back to the story.

Basically, she was okay for a long time, sleeping by herself, and then all of a sudden, she’s scared again. My older sister had to sleep with her one time because my mom insisted. Another time, my mom slept with her because she was scared. I was just in my bed, which was literally IN THE SAME ROOM.

Okay, so after they left, that’s when she started waking me up in the middle of the night, and I just told her to go to sleep. One night, specifically three nights ago, she came up to me, saying she had a supposed “nightmare.” I let her sleep in my bed, being nice. She is VERY annoying, especially sharing a room with her.

She acts differently with the rest of the family than when she is with me. That’s very frustrating, so often I’m mean. Lately, I’ve laid off on hitting her when she hits me. Why? One, because she’ll cry, I’m stronger and WAY older than her, she’s only six. Two, because I thought my mom would have my back. I was wrong.

OKAY, back to the story, so tonight SHE LITERALLY CAME INTO MY BED WITHOUT MY PERMISSION, AND WHEN I WOKE UP AND TRIED TO KICK HER OFF, MY MOM SAID I’M ALWAYS MEAN TO HER AND GAVE HER A BLANKET ON MY BED! OH, AND GET THIS, SHE SAID SHE COULD DO IT AGAIN TONIGHT!! LIKE HELL NO, TAKE YOUR CHILD TO YOUR ROOM! Help!
