Sweetie my Uncle Billy also has Parkinsons disease. I know how terrifying it can be! Honestly though, he was like her, he got worse in a short amount of time and they tried a few things with him and though he still shakes some the disease has slowed. He is now working 2 jobs and doing pretty good. He was diagnosed about 6 yrs ago and he's done amazingly well. Praying for you and your mom sweetie. And you just stay strong and pray also. Never give up faith! Always here if you need to talk xoxox
