My dad passed away suddenly 6 years ago and I was in a similar situation - I the eldest child, and had to care for my elderly mom in fragile health. To top it off I was in the midst of a startup and in severe financial stress. Wait there's more, I also had a nasty breakup due to all this stress. So I hope my story gives you some comfort. My advice is likely contrary to what others have posted and I really don't have any fancy <n> step process, the one thing I did was to take one day at a time, and threw myself into work. (Luckily my startup got off the ground and is running smoothly) But I never showed grief or weakness to my family, comforted my siblings and being a pillar to the family, even though I was shattered inside (I LOVED and ADORED my dad). I gained comfort in seeing my mom & family heal and laugh again. I also started doing mindfulness meditation during this period and it helped calm me down a lot. tl;dr: everyone has their own way of dealing with such events, mine was to hunker down and immerse myself into work & meditation. Hope that helps and sorry for your loss. It will heal over time.
