I don't like my job anymore. Should I quit or continue doing it?

It depends on the costs vs. the benefit. If it offers financial stability I would suggest not quitting until you can find an alternate job that satisfies you.

All jobs wind up becoming monotonous. The issue is, is it simply cause it's boring and it's a job, or is it because of other issues such as disrespect, a bad atmosphere, etc? Weigh the negatives against the positives and that can make a decision. For me, I decided to quit a job based on certain things: immoral issues (I got sexually abused or bullied and then my job was threatened when I complained) and illegal issues (Abused for having a disability and all men were paid more than the women regardless of experience), etc. Jobs always become boring, even when you love what you do. It just depends on whether you need stability or a certain amount of money; etc.

It's hard to leave your comfort zone and rise above. People will tell you happiness is a lie and that to survive you have to work hard. But do you want to survive or LIVE? There maybe financial problems holding you back, but doing what you really love will bring you more happiness and naturally you'll do better at it.

I would continue your job until you have another job setup,

While learning to stay with uneasy emotions, I realized that I didn’t need to find a speedy resolution for the difficult feelings. It’s okay to feel lonely; it’s just one of our many human emotions.

I would first try to make sure there is another job set up seeing that there are financial, social, and health related ramifications the could occur.

You sound as though you are at a cross roads in your life/career, and are unsure as to what to do next? Perhaps you could construct a pro/cons. List this may help you to focus on the situation? Good luck.

You should never stay in a job that makes you unhappy. however you need to be able to live, have food, water a bed and if that job is giving you this you may need to stay in it until you have another option to support yourself financially.

Unless you can afford to live without work for a while, or your job is intolerable and making you severely unhappy or ill, consider keeping the job while you start looking for a new one. Also, think about why you don't like it anymore. Did they job change? Or have you changed? Maybe both? This will help you find a job more to your liking.
