not sure is it just me or maybe other as well lol

recently finished my phd (thou the symptoms showed up even before) and about to carry on with my postdoc, and feel like i lose most of my interests and passion towards most other stuffs, like my everyday life, hobbies etc.

the only thing that could still keep my "excited" is just to keep on working on my project and solving the problems along the way, otherwise most other stuffs i just can't feel the "excitement" anymore.

maybe some of my hobbies can help but like they are kinda transient ? like after a football game, or after a movie...

i feel like i need to extract or isolate myself from my work for sure but found it really hard...

like the moment i stopped working, i felt bored straightaway, and most other conventional "kill-time" like going out, eating, whatsoever, cannot really satisfy my need...

anyone has any idea or experiences something similar ?

thanks
