There is nothing about learning how basic data structures and algorithms work that won't help you in your day to day development.
You might be "fine" without it in a certain category of job, but rather than be dismissive about it you could be excited about having a massive wealth of information that you can use to do your job better.
There will always be something else to learn, wether it be how to apply Domain Driven Design to your work or how to work with graphs when munging data.
It's always worth it.
Just like the other non programming book on the list(Thinking Fast and Slow) GEB is a lot about perception to me.
Understanding that nothing is purely logical nor is it purely expressionistic; by pigeonholing your perception of any design whether it be Code, Math or Art to either Logic xor Expression you are blinding yourself
The other angle for GEB is design
I read GEB along with Design of Design years ago following my mentor at the times suggestion, I would highly recommend doing this.
Think of it as the Gödel, Escher, Bach, Brooks (Although Brook's writing style can be laborious at times)
Recognizing patterns in all design work helped my understand my own design process better.
I respect that, and accept that you have the right to your own life.
You and your life have had great meaning to me and I will forever be thankful for that.
I'd suggest you pay a visit to your nearest ER and have the staff there give you some advice.
Melancholic depression, fairly often is a symptom of other known health problems, that we as humans have ways of alleviating.
I'm sure you've spent time and effort towards trying to solve what you are wrestling with now, but if you would like to give it one more chance the best possible thing you could do is pay your nearest ER a visit.
