Rebekah Gregory, whose injuries from the 2013 Boston Marathon bombing forced doctors to amputate her left leg below the knee, posted a public note to accused bomber Dzhokhar Tsarnaev to say she’s no longer afraid.

Gregory, one of the first witnesses called in the bombing trial, wrote the note after her dramatic appearance on the federal witness stand Wednesday.

Tsarnaev faces a slew of charges related to the two explosions that killed three and injured more than 260.

“Up until now, I have been truly scared of you and because of this, fearful of everything else people might be capable of,” she posted on Facebook. “But today, all that changed. Because this afternoon, I got to walk into a courtroom and take my place at the witness stand, just a few feet away from where you were sitting. (I was WALKING. Did you get that?)”

She added “I looked you right in the face….and realized I wasn’t afraid anymore. And today I realized that sitting across from you was somehow the crazy kind of step forward that I needed all along.”
