age: 24, male had severe head injuries but I never bled on any of those injuries. Most of those hits were directly on the back of skull and on top. I'm having anxiety, mood-swings, agitation, frustration issues a lot. Slurred speech, improper sleep timings, sudden ringing in ears with dizziness that will be there for a couple of minutes, answering questions late than usual time even if I know the answer. Please help me. Should I worry about it that much.
