Here’s the thing about SV: There’s no “losing”. No a right way, or a wrong way to play.
You have the time limit of the day, but there’s no time limit of the game. If you don’t plant a lot or make much cash for an entire in game year, it doesn’t matter. Just go fight in the caves, or fish, or go around talking to people and getting relationships or whatever. The day is in a hurry, but you don’t have to be in one.
That said; your direct complaint is “I have to do it myself?” Well, yes. There is a somewhat driving factor in the game, and that is that just like in real life, you’re trying to do work now, so you can do less work later. The driving factor of the game is completing the stories and also upgrading your stuff so the work is easier.
But again, there isn’t much of a time limit.
Also, it’s a farming game. Did you not expect to farm?
Game progression leads to lots of automation. But like I said, you can “beat” the game doing almost no farming at all if you’d like.
