How do shy people make friends at work?

I want to know how shy people make friends. I’m curious to know what they think and do.

I don’t have friends at job as I’m shy. No one bothers to try connect with me or talk to me daily to open up , nothing. I cannot approach people and make small talk. I will smile and be nice reply 3 words if someone talks to me but after that they never approach me again and I see them screaming saying a million sentences with someone else.
if someone says something my mind is blank and I don't know what to say back.
it was easy talk to ex boyfriend because since he liked me , he talked back easily to anything I would say and we would connect bond.
but at work no one tries bond with me or pursue me daily to talk like a boyfriend would with me. Or only guys that like you would pursue you as a friend at job? Which is why I have no one pursuing me as a friend daily?
