Same thing, ish, here. I don't know if my experience is anecdotal but this gets easier with age. I can hypothesize that I did a lot of unpacking and that my experiences today are much more net positive, thus drifting my "default state" farther from a depressive mindset. Mushrooms helped, but I'd recommend anyone looking into mushrooms, or psychedelics in general, to be cognizant that dealing with trauma in a trip can either be really great or really terrifying. You also are largely not in the driver's seat when dealing with trauma in a trip and fighting it will make things worse. The latter being a lesson I've learned many times over at this point.
