Former reality star Josh Seiter told fans Tuesday that he is "alive and well" after a post announced his "unexpected passing" on Monday.

"My account was hacked," Seiter said in a video uploaded to his social media account on Instagram. "I've been trying desperately for the last 24 hours to get into it."

"Somebody was playing a cruel joke and mocking my mental illness and the struggles I’ve gone through with depression and suicide attempts, and I’m sorry for all the pain they’ve caused when they made the post," he added.

On Monday, his account stated in a since-deleted post, "It is with an extremely heavy heart that we share the tragic news of Joshua's unexpected passing."

Seiter regularly discusses his mental health struggles on social media. In June, he shared a post to celebrate three years and eight months of sobriety.

In July, Seiter shared with his Instagram fans, "When I was 21 I was completely catatonic and committed to a psychiatric ward. When I was 22 I tried taking my own life. At 23 I underwent electroshock therapy. Later that year I harnessed every bit of strength I had and applied to law school."

He added, "At 25 I graduated law school top of my class. By 30 I became one of the most followed mental health advocates online and one of the top creators on OF. At almost 36, life is pretty dang near perfect. Never, ever give up. Your story isn’t written yet. Every chapter is leading to a more perfect ending. I promise."
