I'm so sorry about your mum's health condition, it seems now like most mothers in Africa is special in Nigeria that I'm aware of as suffering from one sickness or the other I can't explain why even my mum is recently having a health issue too but by God grace she will definitely be fine, it might only take a while. mothers are selfless lovers to their children and will go any length to make their children happy even if it means sacrificing their own happiness that's why I always pray to God to put a smile on my mother's face and all the mothers facing the same health issue , they are healed.
