It's been a year since the devastating terror attack that claimed 22 lives and injured hundreds more outside of the Manchester Arena following Ariana Grande's May 22, 2017 tour stop.

Since then, the heartbroken pop star has embarked on a journey of deep healing, both for herself and her fans.

On Tuesday, Grande shared a message of hope on the anniversary of the attack, writing on Twitter, "Thinking of you all today and every day. I love you with all of me and am sending you all of the light and warmth I have to offer on this challenging day."

The singer included an emoji of a bee, a symbol of pride for the city of Manchester, which also appears briefly in the music video for "No Tears Left to Cry."

The emotional fallout from the Manchester Arena incident has weighed heavily on Grande's heart over the past year.

"The processing part is going to take forever. I don’t want to give [what happened] that much power — something so negative. It’s the absolute worst of humanity. That’s why I did my best to react the way I did. The last thing I would ever want is for my fans to see something like that happen and think it won," she told TIME magazine this month.

"Music is supposed to be the safest thing in the world. I think that’s why it’s still so heavy on my heart every single day. I wish there was more that I could fix," Grande continued. "You think with time it’ll become easier to talk about. Or you’ll make peace with it. But every day I wait for that peace to come and it’s still very painful."
