Without knowing your specific circumstances, another thing to consider is that it's possible that didn't have a scientific approach to measure the precise mass of LSD that you ingested for any or all of your trips. Perhaps you were "lucky" in the sense that you never (inadvertently) received an extra strong dose. And, your biochemistry might be more tolerant to LSD.
Dosage affects everyone differently, hence the current wisdom to play it safe by scaling up dosage systematically.
Anecdote or not, and regardless of the causality argument, taking a substance can "catalyze" such conditions to use your wording. There are numerous accounts of people who truly were/are "never the same" after taking LSD or similar substances.
It's important for people to understand this, because of chicken vs. egg. If someone has such a predisposition and isn't aware of it, they might engage in ingesting such substances under the pretense that a substance cannot "cause" a mental illness, meanwhile believing there's no way they could have any such disposition. Contrarily, understanding that these chemicals absolutely are permanently-life altering, regardless of any pre-disposition, is probably the most important thing to consider when weighing pros vs. cons.
Speak to anyone who has taken LSD or similar. Whether good or bad, whether the person is mentally stable or not, the common thread is that changes in mentality/perception from taking these substances are permanent.
