No you don't, I struggles with these same insecurities when I was younger....In fact, I sit up some nights thinking about retarded shit I've done that even though I feel no one else remembers, I defeinitely remember and still feel like "wtf, why did I do that" like the time my friend had studio time to record his song, and the shit was going nowhere...So I jumped on the mic and started rapping. No one seemed to care, and my friends was just sitting back writing in his pad, and we all had fun.....But when I got home I was like "omfg, wtf is wrong with you....They all hate you now"
I have literally hundreds....NO LIE....HUNDREDS of these stories and the keep me awake at how awkward I'm "think" I made situations.
