I'm a teenager, too, and I've been stuttering my whole life. Unfortunately I don't have any suggestions except speech therapy, which I keep plugging away at hoping it will pay off eventually. My stutter is really bad and it can really do a number on your self confidence. It's really frustrating when I see other people my age enjoying their teenage years and talking to girls and having conversation and participating in activities that require speaking. No one else even gives a second thought to how easily their words flow out, while I have no choice except to be on the sidelines either mute or humiliated. Anyway, I can't really help, but I can definitely sympathize.
