I share your pain my friend. I've been waiting patiently 8 years for a new job back in my professional field and last week I was offered one in Poplar Bluff MO. Double my current crappy state salary, take home vehicle, cell phone etc. I went back for a second interview and they asked me what number it would take to get me there. I was on Cloud 9, never been treated that way in my life. I toured the town, they showed me areas to live, discussed benefits, the whole deal. At the end (close to 9 pm) the board chair told me to think on it to which I replied "I want the job, no doubt." He said they would "meet tomorrow night and get it approved." Next night he calls and tells me they went with another candidate. I thought this was a done deal.
Talk about being down, man I was walking on air only to have the rug yanked out from under me. It hurt (and still hurts). I guess the thing is we can't do anything about life in general other than bite the bullet and move on. I hope things pick up for you. This adulting thing sucks balls.
