EMB-145 Flight Attendant reported a diversion due to weather at the destination and a flap malfunction. The aircraft safely landed at the diversion airport.

Narrative

When landing into ZZZ; there was bad weather which caused bad turbulence. My Captain advised me of the turbulence. As we were landing; I heard the 100 ft. and then was expecting to land; but suddenly felt the airplane shift and fly back up. I then received a call from my Captain notifying me that we had a maintenance issue and was asked if I was ready to receive a safety briefing. My Captain advised me of the time we had left before landing - no bracing signals or cabin preparation; just prepare the cabin for a fast; hard braking landing. I remained calm with a smile; and informed the passengers that we were delayed and could not land because of weather and that we will be landing within 10 minutes. I tried my best to keep everyone calm and kept reassuring the passengers as they were starting to worry and get upset. I informed all passengers to remain seated with their seat belts fastened and what to expect of landing. The pilots did a great job of communicating and updating me while dealing with the situation. They kept me very informed. We were diverted to ZZZ1 because the runway was longer for landing. When we landed; it was a very hard brake. We then parked at a gate and deplaned. I was then notified that the flaps on the plane were broken as to why we couldn't land. During this experience; my pilots handled the situation amazing.
