Major Venting & Whatever Else

You know I don't know what could be wrong with me today somehow.  Our weather here is miserable but I've never ever been affected by the weather so........
I'm having a day where the only way I can describe it is I'd like to crawl under something & pretend it's not real.  I'm sort of, I don't know, angry at the whole world, frustrated with most of the world, just would like to scream for no reason at all, would like to take most of my family & give them all a good shaking.  Need I say more.
I've no idea why though & I guess thats whats frustrating me even more.
Hubby's post pneumonia checkup went well.  If the x-rays show anything they'll let us know.  Now tomorrow afternoon we've got the cardiac/pulmonary fuction testing so somehow I need to reverse my thinking today & focus on positive if I can find any positive buried in me anywhere.
I was positive there was more I needed to get down in print here but somehow the brain feels empty & I can't seem to think of what it was.
Oh yea - I happened to catch a moment on TV where they were saying that to aid the ability sleep well that you need more serotonin which intrigued me so I'm thinking I need to research foods, if there are any, that have serotonin & maybe at least my sleep issues can move towards a positive.
