Sharing Our Innermost Thoughts

Hi, whoever’s reading this stupid rant, how 's your day going? So, I was talking to someone, a person, who I’m not exactly best friends with but she’s a part of my friend group, so I usually make the normal talk. I’m friendly, I have nothing against her. But the thing is I have a habit. I’m not trying to brag or show off, I swear but sometimes I use different, complicated english words. I promise I’m not trying to boast or anything but it’s a habit I’ve had since covid took up my time and I read new books back then. So, I’d try to make use of such words, you know, so I could learn more. So, this girl, she told me that I act like I know everything and that I’m extremely intelligent but in reality I’m very dumb. Then she said that I only act like I know everything because I know complicated words. Then she repeatedly kept telling me that I’m not smart but I’m actually very dumb and that I should stop acting like I am smart. I felt very small. Like I know I’m dumb but sometimes when I get creative or think of something I feel smart. But I know I’m stupid. And maybe I act like I know a lot of things, but that’s just a little trick to help with my self-esteem. For some reason, I felt like she was right, and that I didn’t deserve all the little confidence-growing talks I have with myself or the self-esteem boosters I try. Was it really stupid of me to act like that?
