Welcome, deceptive illusion ! You deserve much respect for that being atheist in a religious community is an evidence of a high degree of mind freedom. 
Don't be bothered by pretending that you are Muslim. Consider it a social attitude not a religious attitude. At all events, all people hide some opinions and creeds no matter they live in secular or religious societies and no matter the leaved their religions or didn't. I know it is so frustrating to be an atheist in a religious family but convince yourself that it is a temporary state which will change in future. Plan firstly to be independent of your family and try to live in another city or district. This will give you a reasonable degree of freedom then, if you can, leave this country totally.
At last, Don't treat your atheism as a religion i.e don't be a very enthusiastic atheist and don't let it be your main trait. Being such kind of an atheist in a religious family is too miserable. Consider the religion around you just a social phenomenon (Too fuckin social phenomenon really, I know. But try however not to be very hostile)
