Okay, I missed this before I saw your newer post.
It sounds like you’re right out of school and are having trouble making friends as an adult. Get in line! We all are. We’re all out here struggling to make connections and it’s hard. You said they’re not making an effort to know you. That is not their jobs. They are there to work. Literally one is getting paid to learn about you. People are feeling you out. They are not going to want to get to know you if you treat work like a club- hunting out the attractive women in the room to distract you from work-getting upset that no one knows enough about you to ask you much…what are you doing to be friendly at work, not creepy to your crush and how are you starting conversations?
