Why am I learning Japanese when I have no one to talk to?

I’m a bit of an introvert and use English at work. Trying to get better at Japanese so taking classes. But it hit me—I can’t improve when I can’t practice what I’ve learned.
I have no Japanese-speaking friends (I used to have a few, but they moved away—and since they don’t keep in touch, maybe they weren’t really friends.) I get by with daily social interactions at stores, etc., but is there a point in studying if I have no friends? I am reconsidering all my life choices now. Why am I posting this..I don’t know.
