Yeah, this is very true. I have a theory that Lyme disease is responsible for a large segment of undiagnosed mental illness in the US. Many people don't know this, but you can develop severe schizophrenia or other mental illness symptoms after having it, even some time later. Has happened to people I knew.

I once looked into the bizarre subreddit communities which harbor those likely suffering from mental illness like r/gangstalking, and the various "morgellons" related (and adjacent) communities. A lot of those people have in common that they are either past/present abusers of stimulants like meth/dextroamphetamines, have had Lyme disease (sometimes more than once), or both.
