I think a lot of people convolute introversion with social anxiety.

My social life vastly improved when I switched to working remotely. When I wasn’t, I was burning all my social energy at work and nights and weekends I’d go into hermit mode. Now I’m sitting on my social charger all day and have the energy to hang out with my friends after work/on weekends. Lots of them don’t believe I’m introverted.

A bartender friend coined the term “closet extrovert” to describe me and I don’t hate it.
