Joie,
I am sorry to hear about your struggles. I have suffered a miscarriage in the past too and I know that it can be a terribly devestating experience. I also have suffered many other tragedies in my life that have caused me to question/doubt/struggle with my faith. I think the hard part is that for me there was really nothing anyone could say that would cause me to be stronger in my faith or not question it. I think it is something that you personally have to come to terms with. One of my favorite Surahs is Inshirah (verily, with difficulty soon comes ease). I guess you just have to believe that Allah truly knows what is best for us. Honestly there are still some things I struggle with, but I have just reached the understanding that although I don't always understand what Allah's plan is, I still try to respect it. I think that it is normal to question the religion, but I think a lot of people are reluctant to admit it. Also it is probably really frustrating when you feel sort of abandoned by the Muslim community, which I can also relate too. I don't know if I'm helping much...but continue to vent and continue to try to talk to people to get it out.
