I've gone through periods on various raw diets of extreme vulnerability and emotional release. alot of it is feeling it out and letting in pass, knowing that it cannot actually harm you.
I think alot of people (from what I've seen) sometimes have a similar experience, that diet helps facilitate some of the deeper work, and NOT that it necessarily gets rid of problems at all, although I do think part of the issue re: anxiety does have to do with physical stuff.
for me it still an ongoing battle to mark down objective improvements and things or else. I don't succumb to depression per se (even though I've been in terrible dark ones in my lifetime) but more of like an ungrateful and pointless take on the whole thing if I don't monitor my thoughts and find activities that bring meaning to my life. Noticing the changes in pain or prowess - while not guarantees of following the right WOE - still have their significance in terms of having power over those (ones) circumstances. Meditating (for lack of a better word) on that can prove very beneficial.
a friend of mine once said that if you can choose three people that you cannot stand completely and can figure out a way to really understand, be more civil, and show support to that person, than you will have developed a greater capacity to show kindness to yourself. It sounds hokey, but it may be one way out of the cycle of constant thoughts/arguments etc...also the traditional ideas about having structure and positive routines and ways to break harmful ones is also of great value.
It may be an issue of priorities but possibly also an acceptance that the diet, physical stress, sunshine - all good things -might be accelerating these kinds of feelings, and even the idea that that is a factor might help with any corresponding guilt or spiraling and just an acceptance that having some or even alot of internal baggage is totally normal.
