Okay as dumb and minor as this sounds, this has actually been bothering me so much. I'm an extremely quiet and reserved person, I barely speak to anyone at all so even the tiniest interaction with someone else means a lot to me. Basically, I was walking to class and surprisingly the girl I liked said "Hi Lyon!" but for some reason my mind was completely blank and I didn't respond. I didn't mean to ignore her, my mind was just on auto pilot. I can't necessarily describe it, it's like my body was there but my mind was non existent. I know I shouldn't be worrying myself too much over as simple as not responding to someone when they say hi, but christ I can't help it. Especially since I like her, which doesn't help either. I've been trying to contact her in social media because I felt like an asshole. Am I simply overthinking it? Am I fine?
