i am a 17 year old male. last year i was in an accident and had a head trauma. after this i had no memories and almost no short term memories. over the the few weeks after my short term memory returned although it was still very bad. i do not know if i was like this before, but since then, while thinking, i have been asking myself question and answering then in my own head. it is a little bit like i am talking to someone in my head. over the past few weeks i have started hearing noices and whispers that no-one else can here. i am getting quite worried and i was wondering if it could be schizophrenia.
