Setting Boundaries with Chatty Coworkers

I think what's frustrating is that as an anti-social introvert, I think most sociable people in the workplace don't understand how draining it is for me to have unnecessary chatter with them. I have a very dynamic role in my office that requires me to communicate with people all day, with little privacy, and I prefer to keep socialization at work work-related because every day at work all I'm doing is trying to conserve my energy and avoid unnecessary chatting so that I can last til the end of the day feeling focused, and without feeling overstimulated; and then when I get out of work in the evening, I can actually live my life with the energy and focus I have left. It's nothing personal, it's a mental bandwidth thing. It's a social battery thing. If I chat with you for 20 minutes about how your dad loves oatmeal but he can't have it because of his diverticulitis, and if I'm also having literally like 10 other similar pointless exhausting conversations with everyone else who walks by my office that day, then I might not have the bandwidth to have sex with my husband that night, or work out, or drive home without getting road rage, or work on my hobbies, or do anything creative, or cook or wash the dishes, or have any reserves left in my social battery to call my own mother. It's an introvert thing. Social Chatters will never get it. I'm almost defensive now about setting my boundaries with chatters at work like it's a fucking sport. Unnecessary chatter feels like an attack that I have to fight my way out of. It IS an attack, on my peace. It literally drains my energy and my vibe. So I must protect myself from it. Lol. Anyone else?!???
