My mom did karate when she was alive. She slipped over and hit her head like 2 feet from the ground on wood.
She got depression, and shot herself with my pa's hunting rifle. Miss her. I'm 27 so it's not as bad as it was at 22 but I was a loser shut in and depressed until 25.
Got into fights, got a criminal record and hurt my chances of employment. So I started a small business door to door and now I'm doing better. Making $55k a year and have 1 employee friend.
Get yourself checked man. Head injuries can literally fuck you over years later...slow brain swelling doctors can't even find until later on.
