God, is my character strong enough yet?

I feel like this last week I have gone through an abnormal amount of "character-building" in the form of one scare after another.  Last Sunday, my little sister had a scare that she might be miscarrying.  We all rushed to her side, and I prayed the whole way to her house, I was so scared.  Then Thursday, my older sister's little girl under went surgery to correct a broken arm that had not healed properly.  Only this time she was halfway across the country and I could NOTHING more than sit at my desk at work and pray.  Then this morning I get a call from Mom that Dad had a mild grade heart attack and they are keeping him in the hospital until Monday when they will do an angiogram.  I'm not sure I can handle anymore character building!!  I'm a weeper, it doesn't take much to set me off and this week has been Niagra Falls!  God, give me peace.  I need your help to get through these emotional times.  Be with my Father in the hospital, how frightening for him and for us, his family!  God, I need to feel your peace.
