So I'm actually pretty embarrassed to post this (hence why it's on my throwaway) and am not sure whether this is something that people can help me with but I felt like just typing it out could be helpful.

So I started out working/doing an internship at a company about a year ago. There's this one colleague that's always been super nice and helpful towards me who I really working or chatting with. There's another colleague that I also really like and have worked with on different project before. When I'm in office we often chat and, also judging by the fact that the both of them took me out to a movie when I finished my internship, I'm confident that they like me to a certain extent too. So overall I really enjoy doing this job and am very happy with these two colleagues.

Now a problem that I'm having is that I get unreasonably jealous when these two colleagues chat together without involving me. There desks are connected so it makes sense that they will talk together, and I know how ridiculous it sounds to be jealous when they chat. But especially on days when they chat a lot but don't chat with me I will just feel like shit afterwards. Now especially the colleague I mentioned first and I message each other outside of work a decent amount too so it's not that I'm scared they don't like me (anymore) but for some reason I can't stop feeling jealous when they talk a lot without involving me.

TLDR: For some reason I can't stop being bothered by two colleagues I like talking with eachother if they don't involve me too even though I know full well that I'm being ridiculous. Not sure how to stop it.
