Feel like I wasted my time in the military?

Does anybody else feel like their time in service was a waste in some sense? I was a welder in the navy for 5 years, and unfortunately went into the military under the notion that welders actually make good money. The caveat to that is that yes, welders can/do make good money, but a majority of them work 60-70 hours a week. Currently utilizing the GI Bill to get a degree in engineering, but the stress is insane with having to do school, and work full time to pay the mortgage and other bills. It'll probably take me around 5-6 years anyhow to get that degree, and that's with 12 credits per semester.

I have had a decent amount of interviews for roles higher than just a basic welder/fabricator, but I never seem to make the cut. Resume and inteview skills are fine as I always ask for feedback, but it typically all boils down to them not really considering the military to be actual experience. Just feeling really lost, trapped, and burnt out and wishing I did something different. I've been out for 2 years, and it really sucks to feel like I had to start over again once I got out. Anybody feel this way? Just super discouraging honestly.
