I am sixteen and I really want to start wearing the hijab (headscarf). I told my parents and at fist they told me its my choice but last night we had this "discussion" thing and they started telling me about all the hardships that come with it, which I understand. But they are mostly worried about me because i am extremely shy (I only really talk to people I have known for a long time). Their scared that people are going to say things to me and I won't be able to defend myself. They also think I will become even more self-concious then I already am because people will be looking at me more. They are also worried about my life in the future because we know this girl that wears hijab and because she does she keeps getting refused when she goes for job interviews. I have been thinking about this for about a year and a half and this summer I finally came to the conclusion that I want to wear it. I don't care what other people think, this is my religion and i can do what I want. I want to please Allah. Please help, I don't know what to do. I thought my parents would support me and cheer me on but they have disappointed me. I know I have the right to not listen to them if they are telling me something that is against Islam but I also do not want to start with them being worried and scared about me.
P.S. I was born muslim. My family is very religious (pray five times a day, fast etc...)
