22 years old college student studying mechanical engineering. I've recently transferred to Uni from a community college, but without too much thought into what I'll be studying. I was just good at math and physics, and I thought I could use those skills towards a career. Most people on this website would say that I 'fell for the STEM meme.'

Now that I'm actually faced with actual engineering courses, I'm beginning to question whether the workload is even worth it. Many of my friends who went into CS are bragging about how their jobs are comfortable and low-stress compared to the engineering jobs, and that sounds like it would've been a better investment towards a career. Or maybe I could've even given up the high-paying jobs to do things I was interested in(translation).
But it's too late to regret now, I only have enough years of financial aid to finish this degree, and I couldn't bear the shame of falling behind my peers anymore since I'm already few years behind.

This constant self-doubt and regret is really killing my motivation and the little passion I had for my studies. At this pace I can only imagine that I'd end up with a minimum wage job or be a NEET whether I finish this degree or not.
Does anyone have advice on overcoming this kind of mental state?
Alternatively, if you're working/studying in the engineering field, what excites you and drives you towards the subject?

I don't hate the subject and I can do the work needed, but I can't stop thinking about the other paths I could've taken.
