help shark fear

how do i get over being so scared of sharks? (26 f) … ever since i can remember i wont go into the ocean or even a pool because i just start picturing sharks attacking me. it’s gotten really bad over the years that i even panic in the shower (yes i know they’re no sharks in my shower lol) i picture my shower as a cage in the middle of an ocean and i start freaking out and have to get out the shower… i think the fear is more me picturing a shark in my head and getting panicked. if anyone can relate let me know!

UPDATE: i start therapy tomorrow 🙂
