In my first job I reached a point where every day I'd wake up and I would quite literally dread the day ahead. It was hard to realise that I was suffering from anxiety and that I actually didn't enjoy what I was doing. I was fresh out of uni and I just thought that that's what all working adults feel like.
Looking back at it it's mind boggling how I didn't quit sooner.
If you are in a similar position consider if you're actually happy at your workplace. It's easy to tell yourself that "it's just a phase" and to "hold out a little longer" - more often than not these phases become the norm.
