i think u r suffering from burnout.
from time to time i experience the same feelings too - extreme
tiredness, not wanting to do anything, jus wan to rest but dunno
how, jus so... sian.. so mellow.. and so sick of familiar things.
jus feel like going somewhere no one noes me, somewhere empty and
vast... but yet i cannot simply let go of the things here.
in any case, i realise tt i realli cannot jus get away from it all
- firstly where can i go? secondly do i haf the means to do so?
thirdly can i go at all?
so i go retreat into my shell (since im a cancerian) and slowly
lick my wounds, alone. luckily my self-recovery mechanism makes
sure i can carry on living quite normally for the time being, and
back to normal soon although i may refrain from interacting with
anyone.
and i realise another thing - tt i find solace from simply going to
the temple to pray during such times..
good luck..
