First off, Holly, I would make every effort to decide for yourself what you really are. Since you've been on this forum, you've been just about every religion known to man. I seriously thought you were LDS at one point, but somewhere along the line, I realized you weren't.
Maybe you could handle the hijab issue this way: Wear it only one day a week, since you're only a Muslim about one day a week anyway. If your family gives you a hard time, tell them you're going to a costume party or something. Now before anybody jumps down my throat, it is not my intention to be disrespectful towards Muslims. I would never ridicule someone's religious clothing. What I have a hard time with is somebody who is a different religion every couple of weeks, and posts questions that sincere believers, like the Muslims who have responded in good faith to your OP, do their best to answer. It's one thing to be undecided, but I don't think that's the game that's being played here.
