Lately I have been feeling progressively worse, very slow and depressed in a way (very unmotivated, exhausted,emotionally flat). Whenever I need to concentrate there is this thick brain fog that I have never had before, I really feel like my IQ is 70 these days, even talking feels difficult. My mind is completely scattered... I was with my friends out and said some stupid things which didn't make really sense logically and realized too late. I cried today because of it, I do not want people to think this is how I am at my normal , especially my new bf. I am also so worried when it comes to my exams next month. My blood tests came yesterday and I have ferritin 5, saturation 8% and mild anemia + significant vitamin d deficiency. Everything else was fine so it has to do something with it. Has anyone else also felt like this at some point? And if so, when and how did it got better?
