I lost my brother about 7 yrs ago and it never gets easier - always a void - I saw him once in a dream - imagine I was overjoyed - he came out of a petrol station after paying for his fuel and told me "can't stop now will get in touch " never did so far - always hurts - we just gotta keep goin?
I don't have a brother, and always wished I did. I can't imagine the pain and grief you and the family are going through. Its a terribly sad and rough time, and yes, it will get better, but not for a long time.
