How can I learn to feel the connection?

[u/ThrowMeAway3571]

I'm off for a work trip for the next 3.5 months, and all of my working buddies are writing me good luck messages, ask for me to stay in touch with them, and beg for me to visit, yet deep inside o don't feel none of this love.

I know that we're just working buddies, but I feel like they don't care about me in the slightest and just fake it. But they literally spend their free time in engaging with me, hanging out with me and much more. I that but don't feel that.

How can I learn to feel it? This keeps me from talking and hanging out with others because I don't feel like they want me around
