Exercise is never pathetic. Any efforts to better yourself are worthwhile. Comparing yourself to others is detrimental. And it's unfair. And superficial. You assume that those you compare yourself to have no challenges. Which of them are struggling silently with their own burdens? Which of them can't read, have an abusive family member, have cancer, etc? Never measure your worth against others. There are a thousand ways that doing so is flawed. If you are struggling with mental health, then get help for your mental health. It might also help with your fluency. Are you seeing an SLP for your speech? Exercises are worthwhile, but having a professional guide you is a whole different level.
