It may just be coincidence. At the start of my candida I too had severe anxiety and panic attacks, followed by derealization. For a long time I ascribed my symptoms to the meds I was on, then I stopped them and the symptoms continued and I too thought it was a lengthy withdrawal. You may have simply been progressing through stages of candida and ascribing the changes in symptoms to various different causes. Your adrenals might be completely healthy; turns out mine were. Do your muscles ache or feel fatigued at all? Do you ever feel drunk? Are you losing your ability to find words and articulate your thoughts? Have you started having any flashbacks or dream-like images invade your thoughts? Please let me know if you're having any of these symptoms. I'd like to learn more about what you're experiencing right now, it just seems too similar for pure chance.
