I am not sure if this is the right subreddit, but its kinda the only one i can think of

Either way, recently i noticed i dont recognise people/friends i know, and idk if thisll make sense or if its just me, but i need to get it off my chest somewhere
I realized i dont recognize their faces when i look at a photo, but i do know who the person is
I realised when i looked at a pic of an ex best friend of mine, i know who she is, i know her name, i know we used to be friends but we arent anymore, all these facts i know, but i dont recognize her as, i guess ex best friend? Her facial features look weird? And im starting to notice this with other friends as well. Ans just now i even had it with my own face? Now i do gotta admit i am a cosplayer, but im not that good to completely change my own facial features to the point that i dont recognize myself anymore 
I am not sure how to word it and idk if its just me or if others experience this too? Idk if its something temporary and im just over thinking and worrying over nothing
