you don't have to be happy all the time.

it's okay to have mixed feelings about your job.

i say this because i started out at a place where i really loved what i was doing. i thought i was incredibly lucky to be doing something i absolutely loved and was half-fearful that this joy would one day slip away.

true enough (like many other things in life), the joy did go. i couldn't figure out why i was unhappy with my job, or bored, or tired, or frustrated, but i was no longer happy 100% of the time. i just wasn't. above all, i couldn't understand why i wasn't happy like i was from before. i had a hard time coping with the fact that things change, and time moves forward, and sometimes things just can't go back to the way it was.

what's not okay, though, is to complain about your job. (or anything at all, but since we're on the topic of work, i'll talk specifically about that)

i spiraled into a series of complaints and victimisation of myself. i blamed others for the situation i was in, the range of emotions i felt, and the hurt i had to go through. it wasn't pretty at all. and to be really honest with you, some parts of me are still stuck in this spiraling abyss. i'm still tempted to put the blame on someone else, because it's easy. but it's not okay. i hurt people in the process. friends and family who loved and cared about me got some edge of my blunt sword. it was not okay at all.

it's okay to have mixed feelings about your job.
talk about it to process your thoughts. try to observe your words, your emotions, and the way you react to things, especially with whatever that's bothering you more than usual. the most important thing you can do in a time like this is to process your thoughts and feelings. you can lick your wounds, you can also occasionally question your situation, but try to steer away from complaining excessively. it really doesn't help.

my point is this: it's okay to have mixed feelings about anything you think you used to enjoy doing. 
feelings are fleeting. things change. time moves forward. nothing stays quite the same over time. this thing you have, it might still be of importance to you even though you're not as happy about it anymore. you don't have to feel happy about it all the time. take some time off to really ask yourself how did you get here in the first place. understand your process, you might just find something rather valuable as compared to joy.
