The comment comes after her break-up from fiance Pete Davidson.
Ariana Grande is opening up about how therapy has helped her.
"Who is Ariana's therapist are they accepting new patients," a fan tweeted.
"Lmaoaoo this is funny as f**k but in all honesty therapy has saved my life so many times," Grande wrote in response. "If you’re afraid to ask for help, don’t be. U don’t have to be in constant pain & u can process trauma."
"I’ve got a lot of work to do but it’s a start to even be aware that it’s possible. ?," Grande added.
The tweet comes the same day that Miller's September death was ruled an accidental overdose brought on by mixing fentanyl, cocaine and alcohol.
The therapy reveal also follows the release of "Thank U, Next," Grande's new surprise song, over the weekend. In the track, Grande mentions a few of her past boyfriends by name, including Davidson, Miller, Big Sean and Ricky Alvarez. On Sunday, Grande assured fans that her exes heard the song before it dropped.
"Thought I'd end up with Sean / But it wasn't a match / Wrote some songs about Ricky / Now I listen and laugh," she sings in the song. "Even almost got married / And for Pete, I'm so thankful / Wish I could say, 'Thank you' to Malcolm / 'Cause he was an angel."
Grande goes on to sing about meeting someone else and "havin' better discussions," before revealing that she's referring to herself. "I've loved and I've lost / But that's not what I see / 'Cause look what I've found / Ain't no need for searching," she croons.
Also over the weekend, Grande thanked fans for making her "feel so not alone."
"Thank u ♡ for hearing me and for making me feel so not alone ?," she wrote. "I truly am grateful. No matter how painful! I’m thankful and I love u. Breathin visual this week too! Thank u, next."
Following the release of the song, Davidson addressed his split with the pop star during the "Weekend Update" segment on Saturday Night Live.
"I know some of you are curious about the breakup, but the truth is, it's nobody's business, but sometimes things just don't work and that's OK," Davidson said. "She's a wonderful, strong person and I genuinely wish her all the happiness in the world."
Last week, a source close to Davidson told ET that he deals with his pain through comedy.
"He's obviously hurt it didn't work out but is doing his best to move on," the source said. "Anyone would be hurt after an engagement was broken off. Pete joked about him and Ariana [when they were together]. So joking about breaking up and their relationship is not new."
