My emotional filters were stripped after my moderate TBI 31 years ago (took a few years to rewire my left temporal and basal frontal lobes). I withdrew from people because I was vulnerable. I wasn't in a relationship, but a few bullies and clueless people at work would joke about me being brain damaged, or called me "drame bamaged" and "brain dead". Each time I felt like I was gut punched. It stopped after a year when I told the bully I was going to contact HR. I was able to get caught up on work and finished my PhD during that year (so I wasn't much fun to be around anyway). Amazing what we can accomplish even when we are a few neurons short of a full deck.
