I've been extremely stressed and disheartened for the past few weeks. I've always loved my job and have tried to do my best at it. But around a month ago when it was finally the time for me to get promoted, it was handed over to somebody else. No matter what I do, I'm always sidelined at work. Despite what happened, I tried to continue my work as it is without complaining, but I just can't shake off the negativity. It has been affecting every part of my life. I've been making mistakes at work, I've gotten cranky, and I can't seem to sleep. Even my partner has been complaining about my behaviour. Why do I have to face failure even though I did my best? I start getting headaches whenever I think about it all. I really wish I didn't have to keep working here like this.
