They help you through what you are going through whether it be in a professional manner or not. In my experience loving contact, whether it be physically or intellectually is a must have. Your family's love is unconditional but when it comes to your significant other that is entirely a different matter. You can either lose something with them or gain something. More often than not lose something because they are not used to the change you have gone through.
Understanding is especially important since anyone and everyone can be so, or at least try to be.
When it comes to the work force this is especially important. Not everyone has to know you have to have a brain injury, but when it comes to employers they should be respectfully told. If you go to work and you start forgetting things or fumbling around you are going to be blamed with not compassion what so ever if your manager has no clue as to what is going on. Believe me, you are going to need it. As for you managers training a brain injured person here are some helpful hints.
