The big "c" took both of my parents. Death or loss isn't anything you can prepare yourself for. It's impossible to tell how you're gonna feel until it happens. My advice is to bury your mother and move on as quickly as possible. No point in sitting around feeling like shit. Mom would much rather see you out and about performing your daily rituals as usual as oppposed to sitting around moping. Godspeed to Mom. She was probably getting tired of this shithole anyway.
