I'm a teenager, too, and have a pretty severe stutter. It sucks so bad to not be able to enjoy life and be social like I want to. I'm trying speech therapy again and giving it my best. I really hope it does something. I don't honestly know what there is to try besides speech therapy. Have you tried that yet? My grandad told me his stutter was at its worst during his teenage years through early college, so I really hope if nothing else mine will at least get a little better with time. I wonder if this is other people's experience too.
