Hitting blocks or being stuck on a word is just the tip of the iceberg in stuttering. Under this are so many emotions bottled up. I realized almost at 20-21 years old about exactly how much negative impact stuttering has on our lives. The low self-esteem, self-confidence, anxiety which becomes a part of our behavior affecting everything else in our lives. Only thing that gives me peace is the fact that one day, this will all end. Life is temporary, and so is our suffering.
