My name is Alicia & I m 18 years old. My Father Left my Mom yesterday and she s been really upset and stressed out because of it all. He isn t living with us, he s with a friend. My Mom s hands and arms won t stop shaking. What does this mean? I m worried it s something awful. All I know is she hasn t aten all day and She has a sugar problem. I found something on the internet stating if you have low blood sugar that your arms will shake on and off. I m not sure if that s is or not. I m just really worried about my Mom, and I want to be sure she s going to be alright.
