i feel that - You’re in the same mess as someone else. It’s like you both

You’re in the same mess as someone else. It’s like you both got kicked by life and you’re like, "Yeah, I know how that feels."

Your friend says, "I failed my math test." You say, "I feel that."

"I got detention again." You say, "I feel that."

"I got no money." You say, "I feel that."
