Jealous (any advice?)

I have never been so attached to my friends like i am now. In my close friend group (we are 4 in total), i have started to feel like myself. I frel like they are my second family. But since I became attached to them, feelings of jealousy have started to appear. When they talk on call/vc without me, this feelign eats me from inside out. I dont feel hate for my friends, but i feel like they might get closer to one another without me, and i might be left behind on the conversations they are having and on the "friend percentage". (Does it make sense?)

What i mean to say is, i realize I might have attachement issues and I am overthinking a lot. I do know they love me. But when they don't give me attention I feel like they are upset or mad at me. I want to correct this problem of mine, but dont want to distance myself from them.
