You absolutely are not alone! I keep thinking about what I teach my students who get upset when they don't understand a new concept: it's okay to make mistakes and not get it right away - it means your brain is growing! Well, I suppose six year old brains adapt and grow much easier than my 40 year old brain but it is a good reminder that discomfort and confusion is a normal part of learning new things.
I like how you mentioned that you've been trying to talk about blockchain and DTL with your wife. Explaining what I am learning to someone else often helps my own understanding and it is not something I have tried yet with this new concept so it was a good prompt for me.
