General Maintenance Action
Human Factors
It was a very early show time XA:30. Once we landed in ZZZ; we had over 2.5 hr wait time for next flight. We had experienced a maintenance issue on the first aircraft after we had already boarded passengers. We had to deplane. Do plane swap; board and taxi out for departure. Just before takeoff another issue with the second aircraft. Return to gate; wait for maintenance decision and deplane. Waiting for another aircraft; that's a third one. Waited in open hot air at the gate area for next crew. Felt nauseous and lightheaded. Impossible to continue. We had been dealing with extreme heat; upset passengers and stress due to maintenance issues. I have long haul COVID symptoms. Get tired faster than before. Coming back to full health is taking time. All together had put me in the mental and physical condition of being unable to continue my work duties at 100%.
Flight Attendant reported fatigue and being unable to perform duties due to multiple return to gate incidents and plane swaps.
