Self conscious

Another reason I get so self conscious around people is because I often meet people that I already probably know a lot about because of things I've heard or observed myself, and most often those people have no idea who I am. I naturally tend to find out things about people without even having to ask around. I guess I am- now, the most overused term in my indie-rock existence- a wallflower. 'You see and you understand'. But ugh, I hate using that term. Nobody would take me seriously if I brought this shit up at school. I felt like stabbing myself the entire day, can you tell?
