For what it's worth, I think that you might be wrestling with issues greater than a choice (or perceived lack of choice) of college major. I would suggest talking to a therapist regarding the boredom and frustration. It sounds like you might be depressed and mourning the loss of what you believed life could have been.

I have a MS in CS, and I work for a zoological nonprofit. It involves a fair amount of coding, but I'm also not chained to a desk. The projects are interesting and also provide a benefit to my community. I get to work on database designs, animal-computer interaction enrichment, microcontroller lighting, ecommerce, sound design, and veterinary equipment. The pay is a far cry from FAANG level, but the benefits are excellent and I've made a great career path for myself.

I was tired of working in a traditional coding role, and I started thinking about how I could use the skills I do have in a more fulfilling way for my community and the things in life I love. In the role I have now, even the boring stuff isn't very boring, because the bottom line is something that I care deeply about.
