Shawn Mendes shared an open letter on Twitter on Tuesday, noting he was worried about people thinking less of him if he told the truth.

He also shared the feeling of either "flying or drowning," before adding that it could be because of his age.

The 23-year-old Canadian singer wrote a lengthy letter, which began: "Sometimes I ask myself what it is that I should be doing with my life and what I always hear in return is 'to tell the truth, to be the truth' I feel like that's a hard thing to do though."

Mendes admitted he was "afraid" of telling the truth because then people might think "less" of him.

"They might become bored of me. So in those moments of feeling low I either put a show or hide," he explained. "The truth, in current form is a 23 year old who constantly feels like he's either flying or drowning. Maybe that's just what it is to be in your 20's idk, or maybe that's just me," he added.

Mendes went on to share that he wanted to show the world "100% true honest unique self and not care what anyone thinks" about him. The singer revealed he felt "free" when he didn’t care about people's opinion of him, even though it was a struggle most of the time.

"The truth is even with so much success I still find it hard to feel like I'm not failing," he explained. "Hyper focused on what I don't have, forgetting to see all that I do."

"The truth is I'm overwhelmed and overstimulated lol," he concluded. "The truth is ALSO that I'm okay. I'm just tryna tell and be the truth. I like to think that maybe me saying this might resonate with some people."

Fans immediately showed their concern for the singer in the comments section. Mendes then posted a separate tweet to inform fans he was alright.

"Im honestly so okay! i just wanna communicate with you guys in a real honest way. so i just typed i big old note out for you lol."

On the work front, Mendes dropped a new music video, "When You're Gone," on March 31.
