Introvert is total bs. All those introverts are spending tons of time socializing online and then are burnt out once it comes to additional socializing outside of their phone.
I'm an introvert, I spend the vast majority of my time with my wife. I rarely talk to others at work, and I almost never comment or interact with anyone on social media. Talking to people in any medium is exhausting.
If so, maybe you should try just being yourself around other people too.
The downside is that deeper friendships take longer to form, but for this introvert, that's fine.
