I have just said a prayer for your niece and her family. I also said one for you and your family. I will say another tonight at bedtime. May the good Lord look after both of your families.
I am another who will ask God to grant mercy to your young niece, for her sake and for the sake of he husband and two babies. Hopefully her age will work in her favor and she will have a complete recovery.
My father just had a stroke two months ago -- he's only 57 years old. Seemed to be in great health and then it just happened out of the blue. He's recovering very well right now!!
Sorry to hear about your niece -- I'll be praying the Lord heals her up quickly!!
Not religious but I'll think good thoughts. A guy's wife had a stroke due to medications not going together and she made a full recovery so there's hope out there...We're with ya.
