confused or overwhelmed

i’m having such a bad time interacting with my friends recently, and it not even just that things are a little weird and i’ve forgotten how to interact with them, i’m just not having as much fun around them as i used to. i can’t tell if i’m just in my own head about it but i feel like all of my closest friends are forming their own groups and i’m getting left behind. i don’t want to mind them spending time together, but it feels like they only spend time with each other. even when we are together it feels like they’d rather be with someone else, and i don’t feel like i know them anymore at least not in the way i once did and i just feel really shit and really lonely and really lost
