D&D is hard. Sure the core of it is straight forward but then things start to add up. It is a game that wants you to care about minutia. How far travelled, distance between two points, the height of dungeons ceilings, how long passed since that spell was cast, how much you ate yesterday. And it wants you to arbitrate spell interactions, players weird schemes and prepare a lot of stuff. Also it wants you to actually run the narrative. Some love this difficulty, find the intricacies challenging and desire to master it all.

The good news is that the behemoth of D&D isn't alone out there. Really lots of good stuff can be found. First problem is knowing what one want to find. Second is finding others that have similar taste to you. But it is doable and a good thing to do is ask for help. Because if it is something we like here it is to talk about ttrpgs. Getting us to shut up... better ask santa for a dragon.
