I used to be quite intelligent. Well, according to my school results, at least. I feel as though my brain is fucked now though...sometimes it's slow and feels as though it's not really functioning properly. I'm mid 20s, but already have greys due to stress. Well, not proper greys in the sense that new ones are growing grey...but existing hairs that literally turned completely white due to stress. I was googling if stress can also kill the neurons in your brain, just as it can kill your hair follicles...turns out there is evidence suggesting stress does destroy the neuron connections, hence fucking up your brain. I'm convinced that has happened to me a bit. I will probably have some sort of degenerative brain disease in the future as a result, it seems
