Brother, you should not look to the people above you, you should look to the people below, every human being has their hardships, some has deadly diseases some can't see some can't walk every single one has a con and the list goes on and on and includes emotional and physical aspects. I have a complete deaf neighbor who knows how to lip read and can sey few words by practice, imagine how many stuff she couldn't do, how many times she was pitied, and she isn't complaining and her condition is worse then ours, and I also have a blind uncle, just imagine how many things he couldn't do like playing sports, and the list goes on, God says 'we will surely scourge you with fear, hunger , scarcity of money and self, and fruits' the verse continues but I will stop here but you got the point. just don't care about your stutter, that is what I am doing. I hope I didn't annoy you and remember we aren't angels we aren't perfect. Peace be upon you Friend
