Well this isn't an emotional problem but it is certainly a predicament. I'm in a position where I'm going to need to quit the job that I started just 3 weeks ago because I absolutely HATE it! (for reasons that I won't go into detail). In spite of hating the job, I do really like and respect my co-workers and superiors, and feel bad that I've ultimately wasted their time by quitting after the training. Not to mention that they'll also have to go through the process of interviewing and hiring again once I leave. I will give them a two week notice but am having trouble motivating myself to do that even though I know that it's more courteous to give the notice as soon as possible because of how uncomfortable that will be. It's a strange situation, but the one thing I know for sure is that this job is already a huge detriment to my physical and mental health and it absolutely MUST be quit as soon as possible because it is a horrible experience.

It may be hard, but you have to do what you have to do. Try to end your employment amicably, help them know you don't mean to be unreliable, and let them know you appreciate them. Put in your two weeks, or even three or four so they know you are doing your best not to shortchange them. Tough it out a little longer and you haven't burned a bridge while still getting out. Good luck!
