Like "I am so sorry to hear this. I know you said your mom has MS, but you might not. Don't borrow trouble before it's a reality. If you get the MRI done and it is, then you can cross that bridge when you get to it. Making yourself so upset in advance is only harming you more. I know it's easy for me to say, but i have learned this lesson the hard way. And i still have issues, but because I have Jesus in my life and my faith, i get thru. Might take me a min.but i get there. Please stay strong and know that you do not walk this path alone. Have Faith, You are in my prayers. Be Blessed"
