The best way to be there is to simply be there. Sit by his side when he needs you. Help him out if he needs it.
Most important of all, take care of and be there for yourself. We can't do much if we aren't taking care of ourselves. I know it is way easi said than done, but if we can do just a little every day, it adds up to a lot.
Hang in. I'm here.
