I've been struggling with anxiety for almost 3 months now. At first it was really bad, but after a visit to therapy about 2 months ago I've been feeling a tiny bit less anxious. However, last Saturday something strange happened. The day before I was having nonstop thoughts about the mind it's self, I tend to overthink things a lot. The next day however, I don't know what it is but, my mind felt slow. I woke up and began questioning where is everyone? At school the classrooms felt empty as it felt that daily someone would go missing. Aside from my dogs and cat no one was at home. I even played some games online and that even felt empty. I felt alone, but my mind was the strangest of all that. It was harder to put together thoughts, and make images in my head. It felt like I couldn't think straight no matter how hard I tried. Thus has been going on for days now and I'm lost on what do. I only recently decided to look it up and found that it may be brain fog. How can I be rid of this, and is it really brain fog or is it something deeper or more serious?
