There was an old ted talk that the lady(who was 🏳️‍🌈) stated there is just hard. Her hard, his hard, their hard, my hard. No point in ranking. I don’t have a lisp but it sounds hard. I’m sorry that you have had a hard time of things because of it. Friends who truly care about you wont even notice it though. This is because you are more important to them than your characteristics.
