With the stress from doing everything because the best days of the year are here, remember that Allah is Al Shakur- The Appreciative One. He appreciates the infinitesimal good that you do.
The prophet Muhammad, may peace be upon him, before his demise, advised us to always have the best expectations of Allah. So expect Allah to reward you for whatever, however much you can do, especially when His favorite days are here. In fact having this grand opinion of Allah, The Sublime One, itself is an act of worship it and of itself. SubhanAllah.
Dont get overwhelmed.
Remember what the prophet said: Actions are but by intentions. If you intended to do your best, thats all that matters, inshaAllah.
