She had nothing to do in her life instead of Krishna. She had Krishna in her mind for 24/7. People used to call her “Mad” also they called her “she's suffering from disease of Love". Because she became crazy for Krishna. And She saw Krishna

everywhere. Even though if there was no Krishna yet she talked with him and other people thought she's talking to herself. She's mad. Other people didn't able to see Krishna when there was no Krishna but she used to see him and talk with him even though when there was no Krishna with her.

normal human beings from that period saw Radha like she became a dead body and she doesn't live on this earth. She became like a statue because of Separation from Krishna and She fainted many times in the pain of separation. This was God leelas.

But yeah, Physically Radha's condition was very poor and became worst if we look Physically.

Her pain of separation is beyond from anyone's imagination. Our Mother Radhika really suffered alot which can't be described even Krishna will fail to describe her pain. It was all divine leelas of RadhaKrishn
