Blogging as a Vocation

I think that I have little to worry about in the way of my blogging becoming a vocation.  I notice that blogs that actually make their authors money are positive.  Always positive.  (Say that like Roz from Monsters Inc.)

I am NOT always positive, hence the name of my other blog Positive Posts from a Pessimist.  Because I am a pessimist.  Which is really hard to reconcile with being a Christian.  For some reason;-\

Have you ever just felt like the weight of life is pressing down on you?  I do.  I have sort of regular issues with being sad.  Cyclical issues.  I also have a problem with letting circumstances weigh heavily on me.  Which is really not okay.  Paul lived a life of hard circumstances.  Maybe that's why he was such a great Apostle.

Anyway,  I am feeling quite "down" so any suggestions for Bible verses that might help me endure hard circumstances would be very, very welcome.
