Falling in love with...

Today I fell. Well more like my legs/knees tightened up and gave out. I was getting into my SUV. Normally I just have a person (my teenage son) help me to get up initially from the scooter.  I stand up, twist and push my toosh on to the seat and I push back with his help. Boom then I'm in seat ready to drive. 
As I started to slip all I could drive was hold on to the steering wheel.  Some ladies came to help then a gentleman.  Finally I was able to push back in seat.  I was very thankful and grateful for their help. And after I got settled I cried like a baby. I was crying bc how helpless I was. This MS got to me today. The first in such a long time. It made me plead/cry/yell at my son that he needs to pay attention to me. Stick by my back. Don't get frozen and scared! After the tears I just have to let him know I don't blame him, but be there.
I'm just afraid that I was confronted with this is what my life could be headed. And I don't like it.  Shyt I'm not going to accept it.
