Here is a quick solution.
It is your TEA: Thoughts, Energy (movement, feelings) and Actions that = happy.
You get to choose. Happy is one thought, one song, one happy movement away.
SMILE – and keep smiling until you feel better. Smiling makes your brain happy.
MUSIC – play your favorite “up-beat” song to shift your feelings.
ASK – a friend how their day is going, and cheer them up. It will help you too.
When you are finished you can get back to work – feeling better!
