Feeling disconnected with my body

I use to be 74kg now I am 51kg it’s 2 years long journey. I am 5’3 so I am planning to get on 48kg. I believe I did in a healthy way. But lately I don’t recognize myself in the mirror while taking selfie. I feel it’s completely different person and not me. But mentally I know it’s me. I take selfies and I miss the fat cute version of myself and I know I look prettier now. I wear different clothes now but I still feel my body in fatter version and I feel like people still see me as a fat person.
Does everyone go through this or am I the only one?
