'The Glass House': Is Robin Losing It, Or Is This A Calculated Strategy? (VIDEO)

Reality shows that package people together in confined spaces can be mentally draining, but is Robin really cracking up after only three weeks in "The Glass House"?

She admitted to not being able to sleep, and viewers got to see her inexplicably scrubbing the floors by hand in the middle of the night. What's strange about that?

"I'm an over-the-top, dramatic person, but I'm not batshit crazy!" she said during a sleep-deprived confessional. "And right now I am and I know it."

Robin was picked as one of America's least liked contestants, alongside Erica -- who was up for the second week in a row. Holly was brought back from Limbo this week, with Apollo getting voted out.

After the challenge, Robin's team lost and it was a battle to see who would join her in Limbo. Jeffrey turned it into a political issue over Andrea voting against gay marriage, but he was only able to rally 5 votes, creating a 5-5 tie with Ashley. Who will return?

Find out when "The Glass House" continues Mondays at 10 p.m. ET on ABC.
