on the verge of breaking recovery

so my favorite childhood author made a new book about the main character being grown now and how she tackles life. but there weren't any trigger warnings in it and she turned out to have a serious ed, which really triggered me. she was talking precisely about how many steps she took, how many calories she ate, about punishing herself and all. I'm in recovery and I really try to avert myself from this mindset, but it really triggered me and I'm nearing relapsing. I tried looking online to see if it got better with her at the end, so I can continue reading without feeling too sad, but apparently it also contains slut shaming and instead of recovering, she will start using drugs. I really don't know how to deal with it and I feel so horrible right now.

I tried taking a shower and asked tried sharing this on edanonymous as well, but it hasn't been approved yet.

How the heck do i deal with this?
