Burned...

So... I have a new job.
and I'm totally unexcited about it. It's not that I've gotten used to not working in the last two weeks. I just feel like I got burned so bad this last time. I'm wondering if it's worth the effort to give my all for a job again.
I've always been a bit of a work-a-holic. I've always loved my job. If I stopped loving it, I swore I would quit. And I did.
But I worked really hard at this one. Tried to make things better. And got continually put down and hurt for it. Any extra initiative I took was displayed as idiocy and I was yelled at and cut down. So much of me is tied to my job. My work ethic. If I'm told I'm not doing a good enough job, I take it that I am not good enough.
I hurt. This is worse than a bad breakup.
Maybe it's just safer to not love my job. I guess I know why people try not to fall in love with anything. It always hurts.
