when i was a kid i almost drowned so i would be nervous getting in the pool ... but since my parents put me in swimming lessons i gained confidence and even joined the swim team wow , good for you finding the courage to overcome your fear ! i can understand why you were nervous after what you went through . yes it was scary . but i 'm grateful for my parents for nipping it in the bud ... sometimes that kind of fear stays with a person for the rest of their life i completely understand . your parents sound like great people .
The near-drowning experience as a kid caused the anxiety.
