... a couple years ago I had an incident where I fell down some stairs and ever since then I have felt slow and not the same as before . The simplest things seem stressful now and I get overwhelmed really easily , does anyone have any advice to offer cuz the symptoms are escalating things like memory loss, easily confused , OCD starting , feeling like my brain is empty , brain gets tired easily , restless sleep, panic attacks , troubles keeping up at work , errors at work , etc....
