Not who you asked, but I have similar experiences with recurring depression throughout my entire life so far, and I get a big boost in capacity to avoid deep depression for months/years just by using a small amount of psychedelic mushrooms every now and then. Not even enough to lose my grip on reality or anything wild like that, just enough to chill and be contemplative for an evening. Literally sustains me for months/years from one session.
I’m looking forward to the scientific community doing more studies on the effects of mushrooms, I truly think they are a potentially massive benefit for some neurotypes.
I’ve read that it’s relatively easy and cheap to grow them yourself from spores you can order online, but I haven’t looked into it yet. Hopefully someone else can chime in with some info.
