Hating and loving something entirely depends on your mindset.
If you keep telling yourself that you hate your job, that you hate waking up at 6 a.m. to arrive in time than you will hate it.
If you would go to sleep with the thought "Tomorrow at work I will have a good time." you would enjoy your work more.
Or get a different job.
>I thought it would make me feel happier and fulfilled
You will need a goal for that.
