Friends who are there for you during the good times are easy to find, but friends that will stay with you through the bad times are rare, and to be treasured.

That’s something that Demi Lovato knows all too well. The singer has never been afraid to talk about her mental health battles – she was diagnosed with bipolar disorder in 2011 and has also spoken about her struggles with drug and alcohol addiction, anorexia, bulimia and self-harm.

Lovato has just posted a touching message about her two best friends, following a holiday the trio took together.

In the Instagram post, she thanks the pair – Sirah and Matthew – for “never leaving me in my darkest moments, for always drying my tears”, jokingly adding: “Even when they’re from watching Moana.”

Lovato continued: “Thank you for being loyal, honest and so grateful for every little thing… like crying because we swam with fish/sharks/stingray and coral reef.

“I’m so lucky to be best friends with two incredible souls who are so talented and creative because it inspires me daily. And you’re so supportive of me and every little thing I do.”

She also credited the pair for being there when she had been abandoned by others: “You’ve travelled across the country to visit me and stayed with me at my house for days on end when I’m struggling to make sure I’m okay but most importantly you never abandoned me like others did when I was going through shit.

“You were there to listen, without judgement and only love and I can never fully express what that means to me. You’re the greatest friends I’ve EVER had and our future together is so bright. I love you both more than you can imagine!!”

She ended by saying that she was her friends’ “biggest fans”.

Talking about our mental health can be difficult for many reasons, so when we do find friends we can discuss it with honestly, it’s something special.

That’s something that TV presenter Fearne Cotton also knows, and in a video for Stylist has given tips on what not to say to a friend with mental health problems.

Knowing we have friends who will be there for us in our darker moments is a comfort, and we know we treasure those friends as much as Lovato treasures hers.
