Positive thinking during a stressful time

Today started out stressful. I got a phone call from my mother at 7am. My heart sank when the phone rang because I was afraid that she was going to tell me that my grandfather had passed on. My momhas been helping my grandmother with my grandfathers care this past week during his last days on earth. Hospice said that the end should come this week or next. The phone call was not about my grandfather, it was about my brother and his family. It turns out that my brothers wife decided to swallow a bottle of pills. My brother had to rush home from work to take her to the hospital so she could get her stomach pumped. My mom rushed straight from my grandparents house to Tucson to help my brother deal with the situation there. My mom will be bringing my brothers 3 kids back home with her tonight. 

I am very upset about this situation. I feel it is very selfish of my sister in law to pull something like this when she knows very well how busy my mother is with her DYING father! I don't want this anger and frustration to build and consume my thoughts. I know it is a waste of energy and does nobody any good, especially me. 

 I am doing my best to fill my thoughts with positive things. I am trying to count my blessings and feel grateful for all the good things in my life.  I am praying for my brothers family. I am hoping that their three children will not be traumatized by this situation.  I am praying that my grandfather can find some peace, peace of mind and peace from pain.  I am hoping that by staying positive I can be of sound mind when my family needs to lean on me.  

Wish me luck....
