AngstyLady I feel like I need to have at least 3-4 days a week where I can just be left alone. I'd much rather watch movies and shows and play video games alone, lol. I'm such a loner.

Me too. If I have too be social, like at a party I'm OK for say 2-4 hours then I suddenly begin to feel exhausted, I need to get away, be on my own. I need to 'Shut Down'.
Its like some sort of overload. If I was a computor I would 'freeze' I need to get away and reboot.
Being social, small talk, being 'smilely' is hard work for me. If I dont get away panic might set in, then I'm frightened of looking strange.
