need help figuring out what to do

my moms sick & we're hopeful she's going to recover, so we're trying to keep her hayday alive but she's been playing long enough to have 19mil points & we have no idea what we're doing? i think my nephews cultivated all of her carrots. so now we need to plant more? is there like a general store we buy these at? is this like animal crossing where we visit peoples town?
