I'm moving and my best friend is acting different like when we hug her hug doesn't seem like she completely mean it, and that makes me sadder and sadder everytime cause maybe I'm not her best friend anymore
Of course she's acting different. You're leaving. It feels weird and uncomfortable for her, and very sad. Try to set your own feelings aside and see it a bit from her perspective once in a while, okay? You know, like best friends do.
