I just logged in because I was going to post an issue I have been struggling with, but I saw this post and just had to comment. I have 2: M and N. The two nasal sounds. These are the absolute worst and sometimes dictate how a situation is going to go. If a conversation starts with one of these letters, the rest of the conversation seems doomed. If they don't, then it's okay until I need to say a word with these letters. By then, the conversation is doomed anyway so I can't win. I wish these letters didn't exist. I struggle on others for sure but these are my "nemesis" letters. "Nemesis" is a word I cannot say clearly except in my head. I wish I could offer advice but I feel the struggle too. Only thing I can say is don't beat yourself up. Then again, it's easier to say that to someone else. Trying saying that to yourself.
