In my experience, it has been extraordinary how parasites have affected my mental, emotional and psychological states.
I've notice it most when taking the worm-killing herbs - Hulda Clark e stuff and Humaworm tabs.
That is not to say that all of my 'symptoms' are the result of parasite activity ... I don't know you, so have to consider that your condition might be the result of something else.
But I'd bet that if you were to thoroughly detox and remove the parasites, you would feel so much lighter and so more ready to be social, jovial and congenial.
I found that the liver flukes caused the most moodiness and antisocial behaviour.
You might want to try some liver flushes, interspersed with anthelmintics. That's what I do. The Liver Flush alone, can remove flukes.
