I would suggest you take a very serious look at genetics.
You may be taking the wrong drugs, dosing, frequency etc. and without proper genetic testing-it is rarely pursued by doctors, as it is very expensive (but there are ways to get around this), very time consuming and very complex (most doctors are totally clueless)- you could be just a "cash cow" for pharmaceuticals-pardon my expression which not aimed at you at all-
with no hope for recovery, just some symptom management at best!
Single "established" med approaches for particular diagnosis like yours,
rarely work well, as the treatment must be highly individualized and taking into consideration : genetic mutations, lifestyle & environmental factors and
If any treating doctor, when taking care of patients like you, think for just one moment, that this is the best that can be done to help them improve their condition(s), s/he is totally out of touch with reality.
As for the Andogel your father suggested, it might help, but do NOT consider any random drug/supplement even if it might show promise , unless proper thorough testing to establish your genotype/phenotype (and a lot more tests) is done! I know he means well.
First place I suggest you look at is MTHFR and CBS mutations, which have numerous variants, but you may identify with some of them, as you will find match certain conditions and symptoms that you have.
Since I have no idea about your medical/biochemical knowledge, I suggest
you- or someone close to you who could act as a coach -either deepen your knowledge in the field of Epigenetics/Nutrigenetics/Nutrigenomics,
or if money is not an object, go to an expert in this field.
Warning: These experts a few and far between and in huge demand, so waiting times are years.
My honest opinion is that if you want a better chance of true recovery and get real answers, seriously consider my suggestion.
If you want any more details let me know, however please note that my
comments and suggestions are intended to replace medical advice.
A good start would be "Introduction to genetics" Wikipedia has a good non-technical article on this subject.
