This. Accepting your stutter and talking about it with the people around you was the best thing I could do back in my 20’s. Once you I did this, the pressure when talking goes away and even if you feel it when you stutter a lot it just gets less and less over time. I’m sorry some of your relatives are a bunch of assholes, but it seems your parents support you, surround yourself with people like that. If someone doesn’t like you because of your stutter it shows their fault not yours. I have come across with people that laughed at it. But they are usually on the dumber side of the intelligence spectrum.
