Aside from all the smart mouthed comments, I feel for you buddy. I have been in a soul sucking job that was "respectable" and paid well, but was draining the life out of me and I hated going into work every friggen day. What did I do? I sucked it up, got some student loans and went back to school to get the degrees I needed. It was tough and hard and I came out deeply in debt but the worse day of school was better than the best day in my former career and I knew I was building towards something. I finished school and landed my dream job in the field I love and have been in it for a dozen years. I look back at my previous career and realized I would have wound up on blood pressure medication and maybe suffered more permanent damage if I had stayed in it.
Nothing wrong with going back for re-training. Although I have to say I was surprised at how many people in my family and surrounding social circle made fun of me for going back to school. Teased me about it to no end. Looking back now with my perspective I realize they were jealous that I "escaped" a shitty job, one that many of them are still stuck in. And am happy and fufilled.
They always say "what what it is you are doing when you procrastinate at your job. Because THAT is what you should be doing"
Best of luck, it isn't easy but it is better.
