New Muslim- Please could you help?

Well welcome aboard:). Sadly, no you have to learn your prayers in Arabic. It might be hard since it's not your mother tounge. But trust me you'll get it down :D. I am pretty sure if you say some things wrong you'll be okay, since you know your new :). And yes i think it's important that you tell your parents you converted, their your parents they need to this. It's not a little deal, it's a whole life changing thing you know. Their your parents they'll accept you for you :), and if they have noting against islam, I'm pretty sure they'll be fine. Good luck With your beautiful new life :)
