Thank for that advice, but I sort of already tried that.
What happened was (I forgot to put this in my original post) last week a bunch of them were planning to come over while I was at school. It was, however, a snow day, and I was in my rom. I woke up and I heard some yelling downstairs in my grandma's room (she live in the east area of the house, she's got the bathroom and bedroom and living room of her own and all that) and I found out from her (she's the only one who supports my mom outright, but she doesn't want to openly confront them) that apparently, a lot of my family comes over and pressures her every few days while I'm at school. I heard a few days later (yesterday, a snow day again. Yay.) the same thing again, so I went down the stairs and I listened in, and it wasn't even pressuring, it was most of my family subliminally demeaning her. I think they're trying to make her think she's an unfit mother so she'll give me up willingly. Anyway, I went in and I told all of them off, and lost my temper when my uncle told me to leave, and I punched him and told him to get out. They haven't been back yet, but it's only been a day. I'm 15, but I'm a lot more attuned to these situations than most kids, and I know that what they're doing is VERY wrong. Do you guys have any advice (other than "don't punch your uncle again?)
