You’re dealing with both impediments and social issues here. This would be difficult for anyone. I highly suggest professional help, but if it’s not available or you are unwilling, the next best thing would be to understand you’re going to need to fail a lot with intentions of getting better, and it may never happen. I’m rooting for you.
Edit: To clarify, speech therapy and general therapy are what you will benefit from.
I was being charitable. It’s now becoming obvious you’re just a finnicky person with bad social skills.
I mean seriously, if I had a friend who got so uppity about some silly way I told time (that was common where I came from), I would have to seriously wonder what was wrong with them.
