‘Summer House’ Star KJ Dillard Received Treatment For Personality Disorder

“Summer House” star KJ Dillard needed mental health treatment after the most recent season of the hit reality show … revealing he was hospitalized shortly after filming wrapped.

The reality TV star made the shocking revelation during the season 10 reunion … telling Andy Cohen he went to the hospital for about a week due to self-harm.

Dillard says doctors diagnosed him with Borderline Personality Disorder … a mental illness that “severely impacts a person’s ability to regulate their emotions” … affecting feelings about themselves and negatively impacting relationships they have with others — according to the National Institute of Mental Health.

He shouted out both Ciara Miller and Mia Calabrese for showing up to support him … revealing the ladies sat at his bedside every day during his hospitalization.

Dillard admits he never dealt with his heavy issues head-on before … choosing to run away from his problems instead. He says he’s grateful to be alive — because he very well could’ve died.

As Dillard began to cry, Jesse Solomon hugged him tightly … and praised Dillard for telling his difficult story.

While a vast majority of the reunion’s first part focused on the shocking romance between Amanda Batula and West Wilson — including the pair maintaining they didn’t sleep together until after dropping a joint statement announcing their relationship on March 31, despite kissing for the first time the previous month.

Part 2 of the shocking reunion comes out Tuesday, June 2 … and Part 3 drops June 9.
