I actually have dyslexia too! My father also had it. It really hurt him when he was younger and in school... but now he's actually a teacher and helps kids with disabilities, especially in reading! Dyslexia is particularly hard when you're in school (all those tests and letters! Ugh!) but it does get better. It's not something that will change your life irreversibly, it's just something you have to learn to live with and it'll make you stronger.
Don't be ashamed! I would recommend getting the help you need and telling anyone if it comes up.
