Why is it so hard to make friends at work?

I just got rehired at my old job. It’s a call center for a bank. The first 2 weeks, everyone bonded and became friends. Except for me. My first time working here, I made a ton of friends. But this time around, only like 2-3 people talked to me. And it was small talk.

Before anyone goes off on me. I’m dealing with my autism. I am a female. And I am a little awkward. I’m just feeling a little blue, I guess. Why is this so hard?
