You don't overcome it. You learn to live with it.
There's so much in life to do and enjoy. It would be better to concentrate on gaining more from your life than to dwell on your past. Things cant always work out they way you want it to, this is a fact of life which manifests in different ways. For us, it's the rejection from our loved ones. As painful as it is, we can learn to accept it.

By the way, you're not required to tell anyone that you're an ex-Muslim or atheist. However, pretending to be a Muslim isn't fun.
I left my family and community for other reasons so I'm off on my own in a new city. It's tough and I'm not dealing with it well. But creating friendships does help.
I agree with mini-me. I won't suggest getting married now and popping out kids to fill the void. Starting a family should come out of love, not loneliness.
