hey i recently converted to Islam on the 11 of November i have thought about it for a while and made sure i was doing the right thing. im only young so my family expect that ill grow out of it soon. although deep down i know i am following the right religion. my close friends are all muslim and are helping me so its not so hard. thing is i have recently been told i have to change my name. i was wondering why i have to change it and what i should change it to. could anyone help me?

thanks x
