Who do you have in your corner to cheer for you, encourage you, and kick you in the butt when you need it? Who makes up your support system? Do you have different people for different issues or areas of your life? Who can you talk to about family issues and not religious? For example, do you get relationship advice from someone who could never give you advice about work problems?
For example, I could only think of one or two people in my personal acquaintance whom I can call up and vent to or dish juicy tales to about the parts of me that are both dirty-minded & atheist (trust me, they aren’t the same part, but they make a nice Venn diagram). One of my confidants is my step-sister and the other is a Christian friend (You heard me right).
I am so grateful to have at least a few people who can understand me and respect me when I let those parts show in full color. Since I keep my loud-mouthed anti-religious rants confined mostly to the internet, a good face-to-face discussion is a balm to type-weary fingers. The crass part of me is just kept under wraps to keep old ladies and naive friends from gasping and blushing all the livelong day. I can be a proper, ladylike individual if it’s appropriate, don’t worry, Miss Manners.
So what about you?

For me, my best friend and my youngest sister are the two people I trust most in the world. I was best man at Allan's wedding – and to be honest, I've had no greater honour in my life. And my kid sister and I are pretty much the same, so we get along quite well. Even if she doesn't listen to me about that no-good boyfriend of hers.
We sisters have to figure those things out for ourselves, sadly
Don't worry though, she hears ya.
I think I lucked out. There is absolutely nothing I can't talk about with my husband. Even when it's about him, or us. When I need advice, say from a woman, you know, someone who understands what it's like to have a vagina (lol) I go to a dear old friend from home who happens to be a Christian, but she and I are like sisters. We've managed to respect each other's philosophical preferences – my Hubs and I are Atheists, she and her hubs are Catholics. It's not so unheard of. Respect and acceptance of each other is what matters.
You're very fortunate in both of them! Sounds great. I love being very close with someone of a different belief system. It proves that there's more to friendship and love than labels and opinions.
You reminded me: I do feel a bit silly not mentioning my boyfriend since he definitely gets the real me. He's my home base! We don't discuss intricacies of theology much, but I'm glad he likes that part of me too and we have atheism in common
