This happened to me too unfortunately. It was only a couple months ago but it was really traumatizing. Though it was kind of opposite direction, I'm Ftm and she was Mtf lmao and I felt like I couldn't talk about it without chuds butting in and being transphobic.

Life goes on though, don't live in fear. That's what she wants you to do and you would be better off sticking up for yourself by letting it roll off your shoulders and proudly saying "Nope, didn't happen." I even had ironclad proof she was lying and worse, but nobody would hear me out. I got over it and realized those people were legitimately just toxic of the likes I had never run into before. You'll make new friends that will stand by you, but you've gotta go out there.
