I'm wondering, Did you ever have you vitamin D levels tested and try to increase them to an optimal level. Did you try fasting on raw vegaetable juices including especially collard and kale juice.
I'd be interested to know what you tried in all because I think it is a bit negative to say you tried everthing under the sun while giving no details. This can be very discourging and removes hope which is vital to success. Without hope you will do nothing or resort to drugs and surgery.
Of course you can only get ideas from a forum and you have to try them yourself to realise if they are true or not.
In particular things like vitamin D can take many months or even over a year to build up to effective levels especially if you take an insufficient dose. Likewise diets can take a very long time depending on how ideal they are.
I recommend a vegetable and apple green juice fast now because I feel that gets the fastest results, but there are also anti-oxidants and anti- inflammatory herbs and supplements that can help and if you persist with these methods over many months and add in relaxation technigues or at least cut back on tiring and stressful activity
I can't beleive anyone will not see significant results.
It is very important to avoid ALL immune suppressant drugs
and also NSAIDS. In fact all drugs, unless you absolutely need them to keep you alive
