Same here, so I made my own. We just had a meeting earlier today actually. There are five people (including me), none of whom I would consider my
bestest friends (yes, I just said "bestest"), and two I didn't even know before today. Other than that, I study the Bible weekly with another friend one-on-one. I set that up too. Take initiative and start a Bible group, or just start by studying one-on-one with someone who's willing. Maybe you'll make a friend in the process
P.S. I'll just add that I'm not the most outgoing person in the world and I could do this, so maybe knowing that gives you some hope
