Great, so all my sheltered planted flowers have reset to dirt piles now as she's been unable to tend to them because she's so tense. She is working as a flower arranger, and is unable to do her job because she's so stressed about not going to work, when she's been working hard.
I'm not familiar with the moodlet, so I don't know whether it means your Sim should continue to Work Hard, ease up to Normal, or take some time off. lt sounds like she might have the Workaholic Lifestyle, so you might consider using the Lifestyle-Go-Poof, Instant Fun, or Moodlet Solver potions from the Reward Store to see if they help. A more permanent solution would be the Carefree trait, which also comes from the Reward Store. You might even consider turning Lifestyles off completely in the Game Settings.
For the gardening, I would suggest hiring a Gardening Service through the phone.
She did have the Workaholic lifestyle, I've removed it with the potion and she all good again, thanks. I just wish they would fix these bugs instead of us having to do these workarounds all the time. The fact that she was upset because she felt she was missing work, but also felt overworked and wanted a vacation, just doesn't make any sense.
