Well if people didn't look down on you for stuttering than they'd look down on you for something else. A percentage of the population are just jerks no matter what you do. Our speech impediment sucks so bad especially when its severe. Your feelings are valid but it doesn't help you. Try to focus on what is good, you can walk, you can see, you live in a free country, you have access to medical care, clean water and good food. There are so many on this earth that would gladly trade places with you despite your stutter.
