Can't Swim

I am a water sign, my birthday is in the summer time. I love being in the water, I simply can not swim. My aunt used to take me to Rutgers and she tried to teach me how to float and swim. Once I went to Atlantic city with my grandmom. I got in the water and sat down. I was about 11 or 12. A wave came and knocked me upside my head and I went under. Thank God I'm tall. I stood up right away and tried to catch my breath. I think that traumatized me.
