Stuttering can make us feel helpless at times. I call this the 'feeling weak factor'. We've all experienced this. It limits us. We want to do things, but get so worried and scared, we end up feeling like we're 7 years old again.
But your not. You're an adult. So it's time to start acting like one. Sure, you had struggles in the past. But don't let that hinder you now or in the future. Refuse to. Tell yourself "I'm strong", "I can do it!", "I have the right to live the life I've always wanted".
Say these words with conviction and courage. Shout them aloud. Keep saying them until you feel empowered.
Continue to do so, until you believe in them.
