Signs that your Passion for Work is Gone

I am sitting here in work and for the first time in I think ever I have come to the realisation that I might lack passion.

The signs are all there;

1. counting down the hours until home time
2. putting off starting on my next work item
3. telling myself I'll book in that meeting tomorrow as I just don't have the mind to do it now
4. wondering how I find myself in this situation
5. questioning my self worth

You see I dropped out of college in my third year, as an engineer and from there put my head down and got to working.

I've worked hard to be where I am, which is why the questions running through my head are concerning me so much. I have nothing put away and I make ok money.

I live close enough to home and I get to see my daughter on a regular basis. Even writing these things down has the voice in my head screaming out "you have it well, stop complaining"

Have I trapped myself or is it all just an illusion, will it pass or is this a sign that I might need to move on?

The feeling of being in over my head is all consuming lately so anyone with any experience of this and their opinion is gladly welcomed.

Thanks
