Self-pity

It is something I have indulged in for sure in the past. I think its a natural phase or first stage reaction to problems in our lives, not all the time but sometimes.
I missed out on a job I applied for recently. It was disappointing because I was shortlisted and had to write an essay on why I wanted the job but apparently the essay revealed my lack of suitability. Well, I have to face the fact that there were others more qualified than me.
It's a bitter pill because I had my heart set on it and jobs like that don't come round often. Not a huge salary but enough to get me out of my current low income rut. And the job would've been interesting and rewarding.
Self-pity is so tempting now. But if I go there, I might be tempted to stay forever. Better to go to the next level in my current job. Exceed and excel. Possibly God wants me to do something else, but I'm not quite sure really. prayers eh. Yeah trust I guess. Just hope this makes me stronger. (in Christ, he hastens to add unless he be accused of self-sufficiency )
But in regard to self-pity generally speaking, I see a lot of us have it. Its very common. Some try to hide it but it still seeps through. Is it human nature to think we alone have it tougher than others? No one knows our pain? "No one felt sorry for me, why should I feel sorry for you?"
