Life is a journey
I share your grieve brother, i can only imagine how much you will miss mama, but you should try all your possible best not to be too down and not for long, LIFE have it's ups and downs, so does it have its gives and takes, grieve brother, it is normal, i have been down that road before and it felt like a halt in time, you should know that mama is resting now up there hoping that you get better and move on to explore, flourish and be happy.
Thank you a lot
