Fall Out Boy lead guitarist Joe Trohman has announced that he is temporarily leaving the band for mental health reasons.

"Without divulging all the details, I must disclose that my mental health has rapidly deteriorated over the past several years," wrote Trohman, who formed Fall Out Boy with Pete Wentz in 2001, in an Instagram post on Wednesday.

"So, to avoid fading away and never returning, I will be taking a break from work which regrettably includes stepping away from Fall Out Boy for a spell."

Trohman's announcement came on the same day Fall Out Boy announced the release of their eighth studio album, "So Much (for) Stardust," which will drop on March 24.

The band also released the first single from the album, "Love From The Other Side," and an accompanying video on the same day.

"It pains me to make this decision, especially when we are releasing a new album that fills me with great pride (the sin I'm most proud of)," continued Trohman, who added that he will "one-hundred percent" be returning to the band in the future.

"In the meantime, I must recover which means putting myself and my mental health first," he said. "Thank you to everyone, including my bandmates and family, for understanding and respecting this difficult, but necessary, decision.

"Smell you sooner than later."
