Hi Amanda,
Get another $12,000 and enroll at Commercial Diving Technologies LLC in Florida. They will train you to become a commercial diver/underwater welder in a few short months. They have an almost 100% placement rate and you will be able to repay the $100k that you wasted. The job market is booming world wide and naturally the pay is sky-high.
If I were only single and could relocate at least temporarily, I would give it a go.
