I have decided that instead of beating myself up over the "one that got away" I just need to keep sending my resume out there and see what comes of it.
Thus, two jobs applied to today. Both would mean a sizable income boost. There are downsides to both of them of course, but upsides as well (besides the money which obviously would help).
Who knows what will come of them but I am cautiously optimistic that something will happen soon.
