I know where you are coming from. I am struggling myself. I am also feeling very frustrated. And I also feel like I have made tons of progress but feel worn down and have some newer symtopms cropping up here and there. Or possibly they were symptoms I had a ways back. The last few weeks for me have been terrible. Some of the symptoms are bearly tolerable. What i can tell myou is that die off wil really tire you out. The body just cannot seem to fight this hard and handle all the regular activities. For me I am anxious again. To the point where I tremble at the least bit of stress or worry. My legs feel shaky or trembly and weak and I have this aweful tight muscle burning thing that makes me feel like I am going to loose it. But the truth is I am alot better than I was. I have seen tons of candida pass out of me. And just today I realized my lead legs and arms sensation has greatly lessened. I used to feel like I wa going to have to sit down while walking the dog and I had to lay down after carrying the laundry up the steps, it simply made my muscles want to collapse. Now I get thru those things easily. No more disorientation, very little brain fog. Many of my symptoms are gone. But new things crop up here and and it is very annoying, scary, makes one wonder about progress and doubt yourself. In any case, I have done alot of research on adrenal fatigue. Truth is that many of the symptoms can come from this. Feeling tired , irregular heart eats, reaction s to food. A wide assortment of seemingly unrelated maladies. Check out this article. Its a must. See if it resonates with you. Let em now what you think.
