Jessie J is hurting after she canceled the rest of her Australian tour due to health issues. The singer admitted that she "cried a lot" after a doctor's order forced her to drop dates in Melbourne, Adelaide and Perth on Tuesday.

"I'm sorry for all the fans I let down," Jessie wrote on Instagram on Friday (March 20). "I f***ing hate that my mind is stronger than my body sometimes. I didn't want to cancel shows but a doc told me I had to. I cried a lot."

The singer suffers from a heart condition known as Wolf-Parkinson-White syndrome, with can cause a fast, irregular heartbeat and can make her feel dizzy or faint. As a result, doctors have warned her to tone down her live performances.

Along with a quote from artist Alex Elle, Jessie used Instagram to post a bunch of thoughts, separating them with lines, titling it "Facts | Feelings | Random things." In her post, she talks about her heart problems, but she says she's healing. She also gives shout-outs to her mom and boyfriend Luke James.

"I am ok | I'm feeling better | I was really unwell | I have slept a lot | I have watched every series of Homeland in bed | I'm addicted to tim tams | I still have a heart problem | Dun dun dun | Papers acting like I didn't know lol | Had it since I was born | But my heart is ok | My body is healing | I don't have to mime to hit my high notes on stage | Who believed it? Fess up! | Made me laugh because it was so choopid | Don't even know where they get these stories from | Maybe from Source and his best mate bullshit | anyway | My Mum flew to Australia to be with me | I love my Mum | She has cooked for me everyday | And held my hand whilst I've been in pain."

For those who don't know, Tim Tams are a chocolate treat made in Australia. She continued:

"Thank you for all your well wishes | I need them | If I could hug every sick person right now I would | Rest and be well | Luke is the love of my life | I'm using these |'s because he uses them and I miss him | Off to bed | *Adlibs* | I just walked into a spider web.... | I want a Tim tam..."

Feel better, Jessie. Eat all the Tim Tams you need.
