Hi, I have problems after concussion (11mths), Ive got highs and lows. PCS consists of bad concentration, speech, read and memory problems, derealization, anxiety, eyes problems, etc. Last week I felt better, but 2 days ago I accidentally hit my head by the fridge door. My anxiety got immediately worse, Im crying very often because my symptoms are back and Im desperated..Everytime its better something bad occurs and Im 'back to square one'. What do you think, is it psychical problem or another concussion?
