Sounds like you’re being pretty hard on yourself. I’ve been coding for 40 years and there’s still so much I don’t know and there always will be. CS degrees are overrated too as are degrees in general. Learn as much as you can on the job. Ask to get involved in things. The resources you have available to you know are immense but you just can’t learn it all. There isn’t time. The market might be crap now but it will return, it always does. There will always be people better are more gifted than you - just try and learn from them
