I've got a visit from cps in 30 minutes

I'm literally so scared because last time I reported something I was 10 (15 now) and they wrote down everything I told them and mailed it to my mom suggesting therapy. What if she stays in the room? None of us will be able to talk about the abuse cause if they do nothing she will know and last time I got beat for it. I have voice messages of her verbal abuse but I don't think it's enough to get taken away. And I'm getting scared cause if they don't take us then I won't be able to defend my siblings against her abuse anymore since her husband has started threatening me if I do anything he will show me, he's much stronger than me and I'm freaking out so bad cause I won't be able to live like this but if they take us I most likely would be separated from my siblings and my cats or friends. Omg I'm so scared for this.

Update: she finally came I wanted to speak so bad but if she didn't take us away my siblings would tell my mom since my mom made her talk to all of us at the same time so we would make sure nobody talked. I gave slight hints while she asked questions like I waited to answer questions and I fiddled alot and didn't look her in her eyes, I also looked away after asking questions bc I couldn't keep the act of "she would never hit us" up and she definitely got suspicious because she kept looking at me in a way. Sorry guys I couldn't do it😞 I really wanted to I'm just scared of my situation of if we don't get taken I'd be beat for talking. Sorry to be a let down
