scabies help, won´t go away since 2 years

Hello,
have anybody scabies won´t go away? I have it for 2 years now and it is horrobil.
I try everything (all chemicals / medicine, all natural things with vaseline and sulfur and with all ethereal oils, with enzyme, with borax, CDL, bleech and so on outside , mixed it in all ways. and inside with ivermectin in a high way, with other medicine for animals, sulfur, bitter herbs, CDL, Borax , Turpentine oil, supplements also probiotica, fermented drinks and so on and with bath with borax, bleech, salt, epson salt and so on. Homoepatic: sulfur, arsenicum album, kali-sulf, sepia, causticum, psorinum, apis, natrium muriaticum, staphisagria, ...) Only the speed of spreading reduced. Now I´m full from toe to scalp. And the horrobil mites are deeper under the skin, so that you can´t see them and the poison don´t reach them enough.
I have no bore tunnel (havn´t also the other family members, but there serveral times ivermectin helps), only some light red spots, sometimes. And all doctors say it is nothing and it is so painfull the stinging, burning and itching. They don´t want to take a skin sample. My blood values shows that I fighting with parasites. And that my immune system is getting fast down. (That I must pay by myself) I have lost 30 kg weight since yet. I can´t anymore. Have anybody an idea? now I use supplements and lachesis C 30 and enzyme spray. Thank you for answering

Lachesis because of (scabies (are in the book for skin diseases for scabies) / heart problems /weaker, faster pulse, edema in the ankles)
