Also, about a trigger, there was and is one (the same one). Around two and a half months ago, I began having constant brain fog and mental fatigue. Because I had no idea what this was, I constantly researched for possibilities. Sadly, there are an oddly low amount of articles describing the probably actual cause of it, the hormonal changes that come with adolescence. As such, I discovered some pretty terrifying diseases, and worried quite a bit about those. After that, I realized that my worries were just brain stimulation, and that my brain just wanted more stimulation so it wouldn't be bored, and so it was probably getting me to look more things up to fuel the fears. Either way, I kept googling for some reason, and am now where I am.
