UGT (UDP) is glucuronidation, essentially your body does not metabolize hormones normally. Most likely you have high DHT/Estrogen. This is called Gilbert's Syndrome.
Finasteride closes 3a-diol in many, this is what metabolizes your DHT. This closes 5 alpha reductase and then there are no neurosteroids.
You have low NADPH, since it all goes to maintaining detoxification pathways, to glutathione, to the immune system, to mitochondria. Hence, your Krebs cycle is closed. The Krebs cycle most likely does not make NADH, but produces NADPH and slows down, this closes the stages in it - ketoglutarate, isocitrate, malate (possibly one, possibly several). Oxalates are removed by citrate (a stage in the Krebs cycle). Therefore, you have symptoms of CFS and the accumulation of oxalates.
NAC is all spent on glutathione, it is greatly depleted, most likely there is very little cysteine too. You can also add NAC, but NAC bypasses regulation, it is better when the body uses all the pathways itself. But you say that sulfur is bad for you, perhaps because there is no thiamine, sulfur is a B1 antagonist.
When you drink probiotics, you do it through the mouth, you pass them through the small intestine, you can't do this, especially if you have SIBO. And you most likely have SIBO because you have problems with bile because of Gilbert. Bile is what kills SIBO. Hence the growth of pathogens in the intestine, imbalance, hence the fungi crawl, all this puts pressure on glutathione and there is no vitamin C, viruses come. Hence the deficiency of B12 may be because SIBO will shut down its synthesis by bacteria.
Probiotics need to be administered rectally, I wrote to you, buy suppositories and try them. Don't buy lacto, lacto produces histamine, you don't need it extra now. Just buy bifidobacteria and try, if this also causes panic, just take B2, the panic should pass.
You need to support glutathione (I described it to you above), manganese should probably be added to minerals. Support glucoronation, for example, calcium D glucorate. And remove bacterial and fungal load in your case c. difficle, SIBO, etc.
For vitamin C and oxalates, add magnesium citrate.
Perhaps your gastrointestinal tract does not digest anything and you need bile acids and acid, so think about HCL and bile.
Approximately what can be done:
1. You can simplify and give a complex of minerals and vitamin B. But I have no idea how you react to copper, iron, zinc, etc.
Add manganese and thiamine separately, because manganese starts B1, and thiamine will make NADPH for you. Perhaps it is worth considering niacin (for IDO / TDO) and riboflavin (for FAD). You do not need to give up carbohydrates, sugar is needed for pentose phosphate.
2. Support glucuronidation - calcium D glucorate.
3. Give betaine HCL and bile acids (TUDCA, for example).
4. Bacteria, fungi - here you determine them yourself, because antibiotics may be needed. If the bacteria have a strong biofilm, you will need things that will push the antibiotic inside. Nattokinase, lactoferrin, etc. Probiotics after antibiotics should be administered via enemas/suppositories, not via the small intestine.
5. It might be worth trying Epsom salts/sodium thiosulfate. This will remove sulfites, if there are problems with them. And also, if there is metal toxicity - chelators
6. Magnesium citrate and malic acid, for the malate and isocitrate stages in the Krebs cycle. Malic acid should also support the liver a little.
Judging by what you write, I think the main problems here are in 2 things. Gilbert's syndrome + infectious load.
If you try, then do everything carefully, with low doses, checking the reaction and slowly increase to normal
