Parkinsonspeed, sorry about your situation. Everyone's body is different and we all have sensitivities to something. You are fortunate to notice it at your young age. I worked in HR for 30 years, with a lot of time in apprenticeship and skilled trades training. Here are a few things to think about: Get a complete physical from a good doctor. You need to establish a baseline for your future medical situation-both health and employment wise. Get you eyes checked as well. No use getting all lined up for a new job and find you flunked the physical due to high blood pressure or poor vision. These things are correctable. Better now than hoping a job is still open after your BP or sight is fixed. Be very wary of private schools. Most are in business to make money first, a distant second is preparing you for a job. A lot of good advice has been presented to you on previous posts. You have more knowledge and skills than you realize. Aa already stated Certified Welding Inspector is a great option. Contact the American Welding Society directly if you are interested. Consider sales in the areas you have experience-welding products, welders, tooling, shop supplies. The main thing is your body gave you a warning,heed it. You are wise to aggressively seek a different work environment. Good luck.
