I think you know in your own mind that a change needs to happen, though it's a big leap of faith. My eldest son got a job with a company that sent him to college to learn to be an electrician. A cost was deducted from his monthly pay & was to be paid back after 2 years if he completed and passed the course. IRC, in the 1st year he did so many days at college & the rest at work. Unfortunately he was made redundant in the 2nd year but carried on with the course. After a short time he was put forward for an interview with a company that was looking for someone who was part way to being trained. He got the job, finished his course and became a maintenance electrician. He learnt how to operate & programme Siemens control systems as well, all of which eventually led to him moving to live & work in America. As you can see from his story there are all sorts of oppurtunites that can come your way when you have a trade that is sort after. So go for it, it's your life & future that you are talking about after all.
