I wanna love this game so much. Have tried multiple times. But every time I am stopped by my horrendous Thalassophobia on Giant's Deep and Dark Bramble. And honestly just everywhere. such a shame, it seems so good.
I know there's a mod that can get rid of basically everything scary for the dark bramble. There's possibly one that modifies giants deep too.
Also if you don't mind a minor spoiler for the content of giants deep:

There isn't anything that can actually harm you under the water. The only creatures I remember are jellyfish and they don't really acknowledge you (no leviathans or anything alla Subnautica)
