I was once in your postion. I too were a social and attentive kid growing up with loads of friends whom I could flawlessly speak with. Then something hit and i began to stutter. One of my worst mistakes is let my stutter define who I was, i've let it control my behaviour, my emotions and my destiny. Nowadays i undergo waves of absolute fluency and stuttering. Stuttering is an odd condition but it can be reduced and in some cases, gone. The day you let your weaknesses define who you are, is the day your dreams ultimately die. Don't give up and everything will be fine. Move forward because it's stupid not to.
