It sucks that you had to go through that. I often wonder how close psychedelics bring you to that same sensation. I've had some harrowing trips where at the end of it all I can think about is mending or bolstering relationships which I will often spend considerable time doing in the days/weeks after. I'll often reach out to people I haven't talked to in months/years just because I suddenly feel like it's important. It obviously wanes though.
