Fast Ball hits head on

Life just threw me for a loop.
My Sister has cancer. 3rd type in 2 years. 
First she had lymphoma in her bowel, than breast cancer, and now this.
She had surgery 3 days ago and had a total hysterectomy. 
Her cancer turned out to be ovarian. 
Prior to this she was caring for our Mom who is 84.
Mom is pretty independent and still living on her own.
The day before my Sister's surgery, Mom passes out cold. Her blood sugar dropped to a dangerous level. 
Mom ended up in the hospital. 
Extremely nervous about my sister, Mom wasn't eating like she should. Mom has type 2 diabetes.
Long story short. 
My Sister needs to heal and remain as stress free worrying about Mom. 
I left home that night and stayed with my Mom for a week. 
It took a lot of convincing, but Mom agreed to come back home with me for a week.
Trying to talk Mom into going back and forth between her house and mine so that we both can have our homes. I wanna try to meet in the middle. 
I thought it was a go, but this morning Mom said that she was going to have a perfect stranger come and live with her because she wants to stay in her home and she doesn't want me to have to leave mine.. 
What do I do now???
Please leave any ideas for me in comments.
HELP!!!!
Mom and I live 3 hrs apart from one another. I also have a full-time job and need to support myself. I can take a 12 week family leave and hold my job open.
Mom knows all this and still wants me to stay put.. Mom thinks she can stay by herself. My Sister and I agree, No way.

When Life Throws You a Curve... Continued

So, I guess, I'm hoping blogger has given me the opportunity to write my thoughts down. Reaching out into cyberspace for understanding.. Searching for anyone who will listen. Possibly make a connection with a reader who has experienced the ugliness as I have.
The  betrayal and emotional manipulation.
I have so many thoughts, so many feelings that I need to get out of my head and heart.
I've been able to avoid this until now.
It's time to let them out and put them behind me and move forward.
To speak the unspoken...
To heal.

When Life Throws You a Curve...

So what happens when life throws you a curve ball?
Do you realize, that the ball speeding toward you is about to smack you upside your head and step out of the way?
Do you grip the bat, close your eyes and swing.... and 
Pray that the bat you hold in your hands will connect and hit the ball as faraway from you as possible? 
Do you strike out?
Maybe you try and the ball still hits you anyway...
Thats what happened to me in the year of 2005. 
Six Years later and my life is still in limbo....
As I look back on those years I realize that I was, am, living my life try to protect myself from getting hit again.
I make sure all I have time for is working, eating, sleeping. I'm in a state of LIMBO.. I'm not getting anywhere except passing time. I can't figure out if I'm using this LIMBO time as healing or morning the loss of the life I had. I dunno.....
