I relate to this so much.
I’m not shy but very much an introvert. Actually very confident. People don’t believe me when I say I’m an introvert as they associate it with being shy.
I’ve also masked it my whole life, and when I was younger wondered why some days I’d feel like a social butterfly and others couldn’t string a sentence together or follow a conversation.
My jobs have always been very social/collaborative and my tank is often completely empty at the end of the day. My personal life then pays the price as I can’t face catching up with friends or family after work, or even at weekends after a busy week.
Trips away are the worst without down time. I always have to share rooms and it ruins me, not even being able to dry my hair without someone chatting to me.
My extrovert friends/colleagues don’t get it. I’ve literally said “can we sit in silence please, I need to recharge” and 2 mins later they’re talking to me again.
I avoid spending time 1–1 with anyone other than immediate family / absolute best friends , as I’d rather there was a third person to help carry the conversation.
I don’t think it’s selfish to address your own needs. But if you want to maintain relationships you do have to realise you need to push yourself. Extroverts need to appreciate the same in reverse (but I’ve never met one who’s even been able to understand the concept of being an introvert, let alone compromise, but that’s for another day 🤣 and I’m sure there are lots reading this who are more thoughtful).
