Stopping in for a quick update...thank you all for your encouragement and for prayers you may have said. :)
A number of factors have all converged to convince me that the best course of action right now is to go forward with a new career course. Transitioning to it is going a little differently than I had previously anticipated, but probably better. Everything toward the new direction is happening so smoothly, it's hard to imagine it going any better. Things related to exiting the old status quo seem to indicate sooner rather than later, so after a lot of thought and consideration, I am going to submit my two week notice.
That's uncharacteristic for me, since I'm the kind of person who will stay way past my "best by" date (ha) in any job whether the job suits me or not...that's how ingrained the loyalty-to-company and work ethic concepts are to me. I'll do this by the book and with no negativity. It's just time. All factors..the hour commute each direction, the expense, the low wages, unavailability of carpooling and public transport options (we have only the one vehicle now), the unpredictability of hours, the night hours, the susceptibility to economic fluctuations with my present job are outweighed by better prospects in EVERY category.
So, it's time to smile, say a prayer of thanks for a pantry in which we've been regularly stockpiling a few things, and thanking my friends here for your wonderful words of wisdom and encouragment.
It's all good...I'm excited, and I've already read through my course materials and am beginning to memorize some of the flashcards with much anticipation.
