Life deals hard blows...I know how tough losing a parent can be...I lost my little brother two months before my dad.  He rode it till the wheels fell off and grabbed the old man's hand.  I don't wish that on anyone....especially a soul so old in a body so young.  I pray that your sister makes a full recovery and that this trial in your life will serve to strengthen your family bonds even if that member has not the same blood or surname...friends can be family...talk to them...don't be like me and have them leave this realm without letting them know you love them often. That if you needed to and hadn't asked for or given forgiveness that you live with that regret.  I'm here for you.
