Please don't say no immediately after someone ask you or offer you something. That's the least first thing you can do. Say that you'll consider it. Yeah, I know that if we dislike our job, it can and separate us from others, so if you really hate you job, quit and find the job you like, but reconsider it if you think it's hard to find the job you want, just hang on there until you got a new job. You maybe in the state to enter menopause (no offense), so you got irritated easily. Try to have some fun, the way you like it. Do something you like, don't just stay at home. Go out and do something out there. And the last but not least, quit being so negative, and say to yourself that you can do it.
