Losing your faith is always a difficult journey. We humans don't deal very well with uncertainty and emotional upheaval. You used to be so sure about everything. There was an answer to everything. And now, there isn't. Religions like Islam are also very routine and ritual based. When you're used to doing certain things in a particular way, it's hard when you're not doing it any more.
Since this is a forum for ex-religionists (is that a word?!) I suppose a number of us would say that you've done a good thing. But like Morpheus said, the only one who can really answer this is you.
Take your time. There'll be ups and downs. As you leave the comfort of one "label" or box, it's easy to want to quickly identify yourself with another. Don't try to be muslim, christian, atheist, agnostic, deist, pagan or any other title. For now, you're on a spiritual journey that's taking you places you've never been and opening your mind to things you've never seen. That's all that matters
