Of course you'll find friends! Like anything though, it takes practice. You didn't say in your post but when you say you are out, do you mean just that you are out of the religion but still believe or are you out, a non beleiver, one of us heathens? I ask because where you are, will have a huge impact on your ability to make new friends. You can go to school, the gym, volunteer at the food bank, used clothing, run the park and join a dance class but none of it will make a bit of difference if your ability to trust is still compromised.
If it's coming, then take heart, you will grow and with that growth comes a peace of mind and an unfailing certainty in you own self. That's better than half the battle. Nice to see you here and welcome!!
