This was sort of my experience with LSD. It just broke me. I fell into a deep depression afterward, but the reason was only partly due to damaging my mind. The other part of it was that the LSD made me realize where my life was going, and how completely unfulfilled I'd end up being in 10-20 years. In that way, it helped me course-correct. I'm healthier, more honest with myself, and got back into college because of the experience.
But it did damage my mind. I have mild to moderate anhedonia now. Weed hits me completely differently now (feels more like strong caffeine + brain fog instead of any pleasure). I lost my desire to write creatively.
Unless you did a thumbprint, you're perfectly fine, no damage. Just get your shit together, that seems to be your takeaway. Sounds like it worked. Now you have to keep working on yourself rather than blaming a harmless drug for your problems.
It's similar to one aspirin vs 10000. Also, people do thumbprints and live normal lives after, I just threw that out as an extreme. LSD is very safe if you're doing normal doses. Most people don't take 10000 doses so I can't really speak to that.
The mechanism for water toxicity is physically displacing ions in the brain, causing osmotic damage. (This also explains why lower amounts of water are safe.) A thumbprint dose of LSD is nowhere near high enough to do something like that.
