This answers a lot of questions. You had told me (I think via PM?) that you were healthy before experimenting with methylation supps. You reported being able to work out. I had assumed you had ME since 98% of people on this board do.
So, to clarify, you're generally healthy, but have gut issues and adrenal issues.
Assuming this is the case (and even assuming it's not), my suggestion would be (once again) to
stop experimenting with methylation supplements. It doesn't make any sense to keep taking the things that made you feel bad in the first place.
Forget about Freddd and his theories of methyl trapping, folate insufficiency or whatever. The more you take methyl supplements, the more you're going to screw yourself up. The only way to get better is to stop and let them wash out of your system. They will eventually wear off. Your body will naturally go back to it's natural state of balance.
Then, your next issue is gut dysbiosis. No matter if you have ME or not, you should always start treatment with the gut.
Methylation supplements will not fix gut dysbiosis. You're taking the wrong supplements.
Your next issue sounds like adrenal fatigue and possibly hypothyroidism. You should be under a doctor's care to address these hormones. You need to get to the root issue of why you have these problems. You may have toxic metals such as mercury and need to chelate those out. You may need to take supplements or medications directly for these problems while you're healing the root cause.
I suggest using the Cutler frequent dose chelation method for chelation and not any other method. If you don't take chelators on a schedule every few hours (the half life of the chelator), you may get mercury redistribution and feel much worse.
Methylation supplements may or may not be helpful for the adrenals and thyroid. They may be helpful for detox support while you're chelating.
My suggestion would be to find a functional medicine doctor to help you with these issues. Functional medicine doctors are regular doctors who are also knowledgeable in naturopathic medicine.
The Institute for Functional Medicine (IFM) has the most comprehensive program for the gut that I have seen anywhere. I was surprised to find a wide selection of practitioners in my area:

They also have basic courses on methylation, which some practitioners may have taken. You should ask prospective doctors if they are experienced with the IFM gut rebuilding program and treating adrenal fatigue and the thyroid. If they know anything about methylation, that's a plus.
Unfortunately, the IFM chelation program is not a frequent dose program. I suggest using the online Cutler frequent dose chelation support groups for this (if it ends up you have to chelate).

As far as why are you having bad reactions to supplements and vegetables - the gut dysbiosis explains this. If you have gut dysbiosis, you probably have leaky gut. If you have leaky gut, you have a leaky blood/brain barrier. So basically anything you eat has a chance of causing a systemic reaction in your body and affecting your brain.
The only way to get out of this is to
treat the gut first. Then if you need more help, you can proceed with other treatments in order. It's like peeling back the layers of an onion. You may need a combination of treatments - gut, adrenal, thyroid, chelation, and fixing any nutrient deficiencies to get total healing. You may or may not need to fix your methylation cycle.
