You are going through a tough time to say the least. However the fact that you are writing about this topic and showing your vulnerable side makes me confident to believe that you are stronger than you think. You sir will get through this take it one day at a time. Do it for your brother and everyone you love around you. I wish you success. And in time be a better uncle than the ones around you. Be the type that will give inspiration to the next generation of breadwinners.
