Why is shading fucking me so hard as a beginner?

I feel so autistic because I for some reason cannot grasp the basic fundamentals of shading. Even after hitting the books for a little bit, I don't see any improvement. Do I keep studying the same stuff and pray for change? Are my resources bad? Replies are much appreciated. (even if it's to call me a fagboat for not attaching my work to the OP)
