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:
"Apparently everything I say is going to be taken the wrong way from this point on in my life. Which is disheartening that people want to make me a villain. So no... I in no way meant that depressed people should just 'stop being sad.'
"I've dealt with depression my whole f--king life so obviously I know that. I'm saying find yourself some help. And don't wait for things to change. You have to go out and get that for yourself. You have to find your own happiness and be willing to get better."
We're just happy to hear her doing better!
