I believe you can't stop because you're so devoted Andi :) teaching is more like a passion to you and not a job. I think you need to slow it down and have sometime for yourself; either to go hiking or to relax in anyway you prefer.

I usually go for a long walk or visit my hometown to escape from reality, it's called 'Heaven Spring' for a reason :)

                                                     Slow Me Down Lord

Slow me down Lord

Ease the pounding of my heart
by the quieting of my mind.

Steady my hurried pace
with a vision of the eternal march of time.
Give me amid the confusion of the day,
the calmness of the eternal hills.

Break the tension of my nerves and muscles
with the soothing music of the singing streams
that live in my memory.

Help me to know the magical restoring power of sleep.

Teach me the art of taking MINUTE vacations,
Of slowing down to look at a flower,
to chat with a friend,
to pat a dog,
to read a few lines of a good book.

Slow me down Lord
and inspire me to send my roots
deep into the soil of life's enduring values
that I may grow toward the stars of my greater destiny.

Sometimes it's really difficult to disconnect !
Be carefull ! Talk to you real friends (in your real life)
deactivate your phone notifications (or switch it off)
go swimming, ice skating, (I know you prefer hiking but doing someting different may be good)
If it doesn't works, one thing to do : learn french ;-)

I think you are producing too much so the only thing you can do according me is consuming more. I mean you could go out for shopping (obviously if money is not a problem for you), go running, preparing a cake or a delicious dish, cleaning you home. By the way, the only think that works for me is shopping and/or cleaning the house.

as we all know, work is always there. so when i am tired, i will stand up and have a rest without thinking about it. whatever we do we should focus.and if i am having a break, just enjoy it.
