Sick of the teasing

Okay guys I have this thing where I always pronounce milk as “melk” and pillow as “ pellow”. I of course didn’t realize it till I got into my teens that I was pronouncing it wrong and honestly feel like it’s one of my worst insecurities. I struggled a lot through out school but always was on the borderline of average and just below average. But since I was always scrapping by in school everyone thought I was fine. Reading, English, and math were always awful and my worst classes the worst grades. I found out that one of my friend’s sister pronounced words the same way as me and she has dyslexia. I’m curious if I have a mild form and that’s why it was never caught. Dyslexia I heard is also genetic which my aunt has it really bad. But I don’t even know where to begin to see if I am. But I think the thing that bugs me the most when people rudely try to correct me with how I say some words when I don’t purposely do it. It’s so embarrassing especially since people correct me in front of other people usually. I even had this rude girl I went to Cosmo school with come correct me when I was with a client. It was embarrassing. I just wish people understood that I’m not pronouncing it that way to annoy them.😢 I have tried working on it but it like a accent that I got from no one I live with or hung around. Has anyone ever had experience with these sort of things when none of your family or friends pronounce words that way?
