I know what you're saying. Losing friends is common. My family wasn't very happy about it at first. But over time they came to accept it. But it took a while. Glad you found people who accept & care for you.
Well, half of my family was already Christian, the other half freaked out. I was the last one they expected... lol
That crowd I hung with are now either dead or on a permanent mental vacation, a far as I know. Perhaps some came to Christ, I hope so. I've lost touch with them all. And I never rejected them, that's the weird thing. They just couldn't handle the invasion of reality I guess.
Now, I actually employ two of my very first 'new' friends, and their wives, in my business. One of them is also the worship leader at church. Little did we know what God had in store for all of us- we were just barely adults back then.
I hope God's love in you, has brought more family members in since your salvation. He's faithful, and you have His promises over your family!
