An acute schizophrenic episode 2-3yrs after injesting LSD

Having a lot of anxiety over this and some panic attacks during sleep.
in July of 72 I was given some type of Halluciginetic, probably LSD. In Oct of that same yr, I had what I proceived to be a flashback, brought on by little sleep and a lot of stress.
IN June of 1973, under similiar conditions of little sleep and a lot of stress,
I had what was diagnosed as an acute schizophrenic episode. No relation to the LSD was ever intertained.
A latter alternitive diagnosis of a personality disorder, inadiquate type was given.

(1) Is it plausable for the LSD ingestion to have caused such an episode during that time line?

(2) Is it more plausable to think, that I could have been ok one moment and the next, start shooting at police and security personnel then lasping into a catatonic stupor, because I had and inadequate personality?

The record shows, that with the exception of preceived manipulation, to keep from going to vietnam. for the reporting of the flashback from LSD,
my history has been preceived by others as quite good.
Your answers may help me to understand what has happened to my life over
the years and at present.
