You haven't been out long, and you just watched the way your brother was treated. You just had lies told about you too by family. Of course the mindchatter hasn't stopped, my friend. You haven't had distance, and I honestly don't think you need a break from here. I think that you get that closure by being here and that your brain needs time and information like found on here to work it out. You can't run from it. Now, maybe taking a week away would help, I don't know, as I did that once and it helped because I was spinning a little too much with the stuff, but ultimately the only way around is through, in my opinion and for what that's worth.
Perhaps you just need to find your voice. I did so through my podcast. Hey, maybe that could help. Would you like to tell your story on the "shunned" podcast? I know the guy that does it. He's a wanker, but he takes his audio out of the interview so it's just you telling your story (well, most of the time) so you don't even have to hear his shrill voice. ;)
Seriously though. My wife had not slept well in almost 2 years since leaving the cult. She sat down, really figured out her story and went through it, told it on my podcast, and she's legitimately slept great ever since. It was quite the realization to her. Everyone that has done so thus far has said how cathartic it is. Maybe it would help. Let me know if you want to try it. I'll be doing some interviews in February and could probably fit you in my friend.
