Hey there, thatisacactus. Just so you don't feel confused, I had to edit your post to just put some paragraph breaks in so I'd be able to read it: it's very difficult (especially for those of us with vision or neuro issues) to read through text without breaks like you submitted, so moving forward, it'd be helpful if you could remember to insert some, please. Thanks!
I'm so sorry that you're in this situation now, and that, from the sounds of things, you've always had a family where you haven't felt safe or loved. I'm sorry that you and your sibling have suffered verbal, physical and emotional abuse. None of this is okay. Once we get you out of immediate crisis, if you'd like to spend more time talking with us for more extended support, we're glad to do that with you. But let's see if we can get you out of danger first, okay?
This is obviously a crisis situation. What I'd suggest is that you call a local organization for people in domestic violence who need immediate help and support. In the event that you don't think of what you're living in as DV, so don't think it's okay for you to use those services, please recognize that if those services feel they can't help you or that you aren't the right recipient of them, they'll likely let you know that and help you find the appropriate services, okay?
I'd suggest starting by getting somewhere safe if you can, and then contacting Women's Refuge
. (And if you can't get anywhere else right now, or are worried about leaving your pets without you, just contact them from where you are.) I've referred others to them in the past before with good results. Their hotline (by phone) is: 0800 REFUGE or 0800 733 843. They offer a lot of different kinds of help and support, including emergency housing/shelter when it's needed, which it sounds like it is, for you.
I'll be here at work another hour or so, so if you want to start there and come back if you need more help, or support while you wait on anything for them, I'm happy to keep an eye out for your posts.
