I applied for a job. Got offer and declined it because was SCARED of a change and the stability I have at the moment... Now I have severe depression that I made mistake declining it... The fear completely took over my mind and rationality of thinking...I do not know how to recover from this mistake. The job was PERFECT...
Is there any way you can go back and accept the job?
If not OP then you need to look at it as a lesson learned (no pun intended) and move on. Your reasoning's for not taking the job are not absurd so don't be too hard on yourself.
Next time you apply for a job just make sure you are prepared to take it. Plus give yourself time. There is nothing wrong with telling a perspective new employer that you would like a few days to think about it. That way you are not making a panicked decision.
