Congratulations for finding yourself on the right path. That is a good first step. Your frustration with what should be and what is may be justified and any thinking person would be experiencing it.
As for dualism between what we believe and what science says, should not exist in Islam because there is no conflict. If Allah created all for us to discover and use for the benefit for mankind, then why should it clash with His Word? There may be some areas difficult to understand right now but we read in the Qur'an as time progresses (and new discoveries are made) mankind is going to attest to the Truth of Allah's Word.
