Is this body dysmorphia?

I have no idea what I look like, I can look in the mirror and see myself just fine but I have no idea what I look like to other people. I constantly obsess with looking at myself from every angle of the mirror just to see what other people are seeing. Some days I feel like I’m skinny other days I’m constantly comparing myself to other women on the street, asking my bf “am I as big as her?” Or “am I small like her?” Of course nobody gives me a straight answer in fear of offending me.
