I don't know whether these particular anxieties will sound reasonable or ridiculous, but I would like to know if there is some way of minimizing them. I am very hesitant to pick up math books and learn the concepts in them because I fear I will forget all of the material I read about. It's a completely irrational fear, as I've proven myself very capable in all of the math classes I've taken, and my recall is very strong. Yet I still find myself, late at night, suddenly thinking that I might have forgotten, say, the formulas for the derivatives of elementary functions, so I will run through the entire list to make sure I remember everything. Every week or so I imagine myself thinking I've forgotten conic sections, so I run through all of the details of those in my head. And so on. Every time it is something I already know (and can recall) that worries me. It's gotten past being a "good study habit" and is becoming a real pain, as it happens quite often. I also do this with novels sometimes, thinking I've forgotten everything about them. Anyone else run into similar issues?
