A Long Island woman’s insistence that President Obama follows her on Twitter made doctors at the Harlem Hospital psych ward think she was delusional and suffering from bipolar disorder — but she was actually telling the truth, a lawsuit charges.

Kam Brock’s frightening eight-day “One Flew Over the Cuckoo’s Nest” ordeal at the mental facility included forced injections of powerful sedatives and demands she down doses of lithium, medical records obtained through her suit filed in Manhattan Federal Court show.

They also indicate that doctors didn’t believe the leader of the free world followed her on Twitter — though @BarackObama follows over 640,000 accounts, including hers. They were also skeptical she worked at a bank, records show.

“I told (the doctor) Obama follows me on Twitter to show her the type of person I am. I’m a good person, a positive person. Obama follows positive people!” Brock, whose Twitter handle is @AkilahBrock, said.
