My family is rejecting me

Hi all. I’ve been a christian about a year now, and my cousin who’s my age has begun to ignore me. I noticed they’d stopped greeting me when we saw each other at events, then I noticed they would make small remarks under their breath when I walked in the room, or not invite me into the group with the rest of the family our age when they went to watch a movie or whatever. I thought maybe I was being too sensitive so didn’t take it personally.

But their birthday just passed and for the first time in our lives, they ignored the birthday text i sent them entirely. I’m heartbroken. I knew there was a high chance this would happen when I turned to Christ, but it’s an eye opener to see people who you thought loved you unconditionally (because you love them) actually switch on you. I’ve never had a lot of friends, my family were my best friends. Honestly, I’m not taking this well. I’m writing here because i have no one to tell. Thanks for reading :(
