hey /out/
i have a fear of deep and dark water, an example is pic related.
i am having trouble overcoming this fear so i would like any help on this

when i am scuba diving and see an endless depth i get stunned and just stare endlessly at how deep it is, this causes me to get super scared and swim away as if a beast is going to emerge out of the darkness.
with a help of a friend i swam close to one of these pits and i couldn't bare it i thought i was going to fall endlessly into the darkness of its void, i lost control and had to pulled up
