Read up Ecclesiastes 3vs 1-2, there is a season for everything, a time to be born and a time to die, I know you're hurting over your mum's demise and the fact she didn't get to live till old age but my dear,be thankful that you got to spend time with her, there are so many humans out there whose mother's died when they're young, those who never felt the love of their mother. The fact they lost their mothers does not mean God does not exist, that doesn't stop them from believing and still praying to God. God is God and he's unquestionable. In the means of tribulations and grief, He is stil God and He changeth not......
Your mum had fought her race and finished strong, it is left for you to move on and get to know God for your self, don't let the devil steal away your joy and put funny thoughts in your mind..... remember the story of job, did he give up on God? No he didn't, so poster, be comforted.....
