To answer your question "Am I crazy to think ... " Yes! (lol). There's nothing wrong with what you have. It's your insecurity and a bit of paranoia speaking, thinking that everyone is looking at your "small" breast, judging you ... You sound like a reasonable person and no, most people do not care. Personally, I would prefere your 34A before something along the lines of 36 DDD. No, seriously, you have nothing to worry about. If someone has a probalem with it, screw them (not literally), they are not worth of your tme. Stop worrying abut it, you are just fine!
