We’re all in this together. Our impediment does make things harder, but doesn’t stop us from being good people. Focus on what you can do to make a contribution to society. Focus on improving your work ethic to realize your potential. Focus on your family and friends around you that you love. A stutter is just added difficulty, but that doesn’t make it impossible to be a good person. If I were you, I would apologize to your mom and let her know why I was actually angry. I’m saying that because I’ve felt the same way with my mom, and letting go my ego always revealed to me more than I expected.
