Today I realized I’m stupid

I’ve been thinking about it for a while but today it really set it. I am stupid. I know next to nothing about everything. I have a college degree in a subject I know little about. I was a 4.0 student through high school and college but I can’t recall anything I learned. I think I’m smart and then I meet people and realize I don’t know anything. At my work, everyone is so intelligent. My husband knows so much. My family is very smart. How do I become smart? I read books. I spend my free time researching various topics. But I guess I just never learn. I can spend months studying something and will still never remember it. I don’t know any history, nothing about politics, am horrible at math, can’t spell, don’t have any basic life skills. I don’t know where I went wrong. I’m just a dumb person. That’s it, that’s the rant.
