Justin Bieber's giving fans an update and it's an honest message, if not a bit sad.

Justin posted a revealing message on Instagram, writing: "Just wanted to keep you guys updated a little bit hopefully what I’m going through will resonate with you guys. Been struggling a lot. Just feeling super disconnected and weird.. I always bounce back so I’m not worried just wanted to reach out and ask for your guys to pray for me. God is faithful and ur prayers really work thanks .. the most human season I’ve ever been in facing my stuff head on."

Bieber is the latest in a string of celebs that have revealed their true struggles with mental health. Kanye, most famously, has talked about being diagnosed as bipolar. In fact Bieber posted a pic to accompany his post of him with Ye and manager Scooter Braun, apparently in prayer. Pete Davidson has admitted to suffering from borderline personality disorder. And a bit closer to home ... Selena Gomez has sought treatment for mental issues, suspected to be depression perhaps stemming from her health struggles and/or from losing her first love, Justin.

Justin's been spending time with Hillsong pastor Carl Lentz -- trying to deal with his issues spiritually and without meds. He's not in rehab, a source tells Us Weekly: "He sees a therapist, but he’s not in a special center or anything. He doesn’t want to be dependent on medication. He struggles with ups and downs, anxiety, depression and uncertainty about the future."

The source says Justin's wife Hailey has been a pillar of support for him: "Hailey is not going to leave Justin and he won’t leave her either. She’s been so supportive of him throughout this process."

Keep Justin in your prayers!
