I just read your history and felt awful for you. I understand totally how it might feel to be in your situation, try anything and everything, and still be getting worse.
I think you are correct about parasites
causing the thyroid issue, and getting rid of the parasites
correcting that problem, it was the case for me.
But.....I wonder if you realize how you just responded to someone who tried to offer advice to you. They spent time to read your message, and type a detailed response as to what has helped them with a similar issue. To label them, or anyone else here as a "wack job" is pretty offending.
You keep trying everything and nothing is working. I see where you believe you have flukes and tapeworm, but don't really have solid evidence of them. You tried some drugs and they didn't work, you tried the herbs, and they didn't work. What if it's roundworm and not tapeworm? The drug you tried would have been the wrong one.
Do you know what you have for sure? Roundworm are very hardy. I have had people tell me they took a,b,c,& d, and got rid of roundworm in a week. Well, I appreciate that, but I also don't believe it. Others say they rid themselves in a few months, but they are still sick from other issues, that could be related to worms.
Sharing ideas and trying to help work things out is what this forum is all about, but I'm hesitant to even comment or suggest, so as to not be labeled a "wack job". At the same time, I understand the stress this can put on you mentally.
Why don't you start over. List what started your health issues, what you have tried, how long you stuck with it, what you saw in your stool, etc. Maybe then you can get some insight or ideas that you can try, with an open mind that we are all different, our bodies respond different, and our parasites
adapt to our individual bodies, not what is on paper or a forum.
