This worked well for me one time-- I was feeling sui and had some extra money for once. Instead of researching methods, I found the cheapest ticket to Europe that week, which was Copenhagen, got a nice airbnb for ten days and just did whatever every day. Only told one or two people where I was, and I told none of them why. I came home still with the same concerns but the self harm crisis was over.

I also had been IP previous to that trip... my experience is mine alone, but it actually made me worse. Which is why I looked for another option.
