Right.... What do i do now??

So.... Suffered a head injury last year, blah blah blah. I thought I was getting better. All the things that were happening because of the head injury stopped after a while.... Or I had just stopped noticing.... I'm hearing things again.... Arguing that isn't really happening, crying that isn't really their. Things breaking, someone running up the stairs. I literally thought someone was breaking in. Turns out. No. Just me hearing shit and losing it.
