How Should I Feel

My brother has been in the hospital since Friday with acute kidney failure and on 24 hour daily dialysis.  His condition is stable right now  but things could change.  We are not as close as we used to be  but I still call and check on him every few weeks.  Mostly because my mom ask me to do it.  I still love my brothers and my sister  but since I moved away  we have not been that close.  But that doesn't mean I don't care about their well being.

My older brother is mad at him because he feels he brought this on himself by drinking too much over the years.  Although he took him to the hospital  he has not checked on him or anything since Friday. I called him today to let him know our brother was stable and he was still fussing that my brother brought this on himself.   Am I wrong to think that no matter the reason we should still care and be concerned about his health? 

I feel like I am always in the middle trying to do the right thing.  I love my siblings even though they don't seem to care about me or each other.  I know that i'm right to care and to try to do whatever I can to help.  But it really gets hard during times like this.
