I was sexually assaulted and my friends didn't take it seriously.

Autumn
I was sexually assaulted after work by a coworker who held a box cutter to my neck and shoved his hands down my pants, fingering me, and pushed me down, making me give him head after telling him NO more times than I can count. They almost laughed it off saying if I didn't want to do that, I just should've ran away. As if I didn't try to get away. And just because it wasn't actual rape, with him forcing his penis into my vagina, they act like it's not a big deal. It's making me question myself as to whether it is a big deal or I'm just over thinking it. It's definitely making me not want to tell anyone else out of fear of not being taken seriously. I don't know what to do. I'm scared every day at work.
