if you don’t take LSD again and cut down on the use of MD these panic attacks are most likely to go away. Although the overblown and inaccurate scare stories of my generation are thankfully not as often believed, younger people are often a bit apprehensive about LSD because it became very easy to get for a while, people did too much in the wrong setting and freaked out and bad news spreads quickly. It is also possible you were in a less than ideal setting, London or any similar large city can be a harsh place (I lived for many years in SE London).
I never had a “bad trip” as such at age 19 but remember me and my mate ended up doing petty crimes and theft which was out of character for us on party drugs and we could have got in trouble. But girls often have more of a social consience than boys and the fact you are doing something “bad” can eat away at you with guilt and subconciously cause bad trips. I’ve noticed over the years the girls on the party scene tend to be more self-critical about their drugs use than many lads and stop earlier. However it is even possible that if you are still interested in parties/music etc by your mid 20s and not caught up with other responsibilities (such as parenthood) you could take LSD again without having bad effects
