I too am sorry to hear that you are struggling atm.
If you are still suffering with a headache...then you may just need to give yourself permission to continue to take things easy...and rest and recover.
However, if you are starting to feel relief, then Hibee's suggestion of a little exercise is a great one! Even just some moderate movement can break you out of a rut and improve mood.
Then I would suggest setting small goals for everyday. Completing a task...even just a small accomplishment that you can cross off your list...boosts motivation. Getting started is often the hardest step...so dig deep and know you can do it.
We are sending encouragement your way!
