The source noted that this is something Justin "has to deal with", and is in fact seeking therapy to help him work through it.
The singer said seeing his now-wife again last June made him realise how much he "loved" her, despite going through a rough breakup when they briefly dated years ago.
PEOPLE reports that one insider revealed, "Justin seems down and exhausted".
"I'm very proud of my family name", she tells the outlet.
However, the source insists that Bieber's struggles are completely unrelated to his marriage to wife Hailey Bieber, whom he reportedly Wednesday secretly in fall 2018. "He seems confident he will feel better soon".
"One of the reasons Hailey knew he needed more help was his sleep patterns", the source says.
"He started off as a typical sweet, Canadian teen".
"He's emotional and struggles a lot with the idea of fame - being followed, having his every move stalked by fans, cameras in his face", the source said.
"I got really depressed on tour", he said of his goal tour in 2017, which he ended up cutting short. 'People love me, I'm the s**t, ' that's honestly what I thought. "He's been sleeping far more than usual, and struggles to get out of bed until very late into the morning or early afternoon". "I was wearing sunglasses inside", he said, then adding that he began to also have "a legitimate problem with sex". I found myself doing things that I was so ashamed of, being super-promiscuous and stuff, and I think I used Xanax because I was so ashamed. News, Bieber is leaning on friends and family to get through it, as he "really wants to get better". "Stuff that they passed on that I'm kind of mad they gave me". "I have loved him for a long time".
