Parasite, bacteria, Lyme, worms - what the hell!!!

I just dont know what I am fighting right now.

Mendeazole had some good effects, goldenseal, herbal cleanses, amoxicillin, ampicillin, doxycycline; all seem to have some effect but nothing is clearing my system.

What kind of entity would be susceptible to all the above?

I feel tingling, pressure etc all around my head, face and nose. My mind is crippled, I can barely think straight and my energy is nil.

Im on a diet of meat, vegetables and small amounts of fruit, nut and granary bread.

Someone please, help me put an end to this awful life.
