I'm sorry but this whole parasite delusion is getting out of hand. Take a few triple stool test (They tend to come back negative) and a eosinophil count in your blood. If you have flukes your fasciola antibodies will be high and your easinophils. If everything is negative you don't have parasites. They are not some invincible and untreatable and undiagnosable enemy. Ask any parasitologist who sees real infections everyday. People have been having worms for millenia it's nothing new.
I recently spoke to a GP who worked 4 years in Zambia, who says parasites are very easy to diagnose and to treat.
He said flukes don't multily in the body, the only way to get a massive burden of flukes is when you get reinfected from the external source (Like eating contaminated watercress regularly)
Besides Borderline (BPD) is well documented it's a personality disorder from the cluster B from the DSMIV, It's in the same group as narcissism and psychopathy. The cause is mostly originating from abuse and neglet in early youth, very sad stories most of the time, hope he get's decent treatment.
