Now, she's opening up again about going back to therapy.
Posting an Instagram story, it read: "Friendly reminder for anyone who needs to hear it: Therapy is never something to feel ashamed of. Everyone can benefit from seeing a therapist. Doesn't matter how old or 'proud' you're trying to be."
She went on to say, "We are all human. And we all struggle. Don't suffer in silence. Don't feel embarrassed to ask for help. I'm 22. I have anxiety and depression. And today I started therapy again. And so the journey of self-love begins for me."
It was in May 2017 that Lili decided to break her silence on the importance of mental health.
She sent out a series of Tweets that said:
"Riverdale came into my life when I was going through the worst depression I had ever experienced. And in the end it completely saved me. Since it's mental health awareness month, I figured it would be good to share that. I worked my ass off to make a living out of what I love.
"And when I'm feeling depressed or sad, I remind myself how far I've come. And how I didn't let my depression consume me... To anyone out there who feels depressed or hopeless... do not f--king give up on yourself.
"You're all you've got. And you deserve the world. Your mental health should be your priority. Don't forget that. This is your life.. and you've only got one. So don't waste it by being sad."
Fans were actually upset by Lili's choice of words at the time, claiming she was saying that depression was a choice.
Lili then responded to the backlash with more tweets:
