I'm not the one that would be able to help you and hope someone here can.
A suggestion would be and I don't know that I'm right but if your symptoms are getting worse, it may be that the meds may be working.
Perhaps the bugs are getting desperate and you are picking that feeling up. I've experienced this phenomenon myself and so have some other brave souls, that posted in these forums, that could stand the cutting remarks that can come for such a 'far out' idea.
I am sorry you are suffering and feeling desperate but I am not all that knowledgeable. Wish I could help!
