Yes, I feel like this. I could scream from the rooftops all day about the medical negligence I've experienced, and of course, family members always trust what the doctors say. Hell, even I did for months on end. I've been to the most prestigious clinics in the country and was told complete rubbish. Mainstream medicine can't be trusted when it comes to parasites, but the good news is that you can take treatment into your own hands. Try a parasite cleanse to start with and see what it does. If it produces anything visible, photograph the evidence! Your husband should not be verbally abusive under any circumstances.
I'm nowhere near recovered yet but I get some degree of satisfaction from pursuing my own treatment and refusing to line these overpaid specialists' pockets. Hit me up on PM if it gets too much - please don't think about taking your life.
