No topic was off-limits.

Selena Gomez has had a rough couple of years, but she's finally found the light at the end of the tunnel, and she couldn't be more grateful for the steps she took to get there. The singer dished about everything from her time in rehab for depression to her relationship with The Weeknd in a new interview with InStyle, and she's never sounded more confident.

"It's so weird, how one year can change everything. Last year I canceled my tour and went away for 90 days, and it was the best thing that I ever could've done. I had no phone, nothing, and I was scared. But it was amazing, and I learned a lot. Everything I cared about, I stopped caring about. I came out, and it felt like, 'OK, I can only go forward.' And there are still days. I go to therapy. I believe in that and talking about where you are. But I'm in a really, really healthy place," she explained of her time in treatment, noting that she loved equine therapy and not having to do her hair while she was there.

The brunette beauty also wanted use her return to the spotlight to highlight the importance of getting help when you need it.

"When I came out, I was asked to go to the American Music Awards, and everyone around me was like, 'Do whatever makes you comfortable.' I didn't want my fans to have a negative view of taking care of yourself, so I just went in head-on, and I'll tell you, the first time stepping on that carpet was so overwhelming. I felt like my back was sweating," she revealed.

She tackled the issue of mental health with her new Netflix series 13 Reasons Why, and she likes that it has gotten people talking about the tough stuff.

"I didn't think it would even remotely blow up the way that it did, both positively and, obviously, controversially. So in Season 2, we answer a lot of the questions that were brought up. And I think if our show is able to start a conversation at the dinner table, even if it's just 'That's terrible' or 'That was great,' it's still starting a conversation. It scared people, but it's really important," she noted.

As for her relationship with The Weeknd?

"It's great. I don't depend on one area of my life to make me happy. It's really important for me to love and nourish my friends and family and to make sure that I never get influenced by a guy. I've wanted to be in a strong headspace for years, and I really wasn't. Before, I was so young and easily influenced, and I'd feel insecure. You want someone to add to your life, not to complete you, if that makes sense. I'm lucky because he’s more of a best friend than anything else," she gushed. Sounds like she learned her lesson with Justin Bieber!

You go, girl!
