I hate pool drains also, but not that much. I also hate dark pools and was afraid of swimming, but I made myself do it and now I love it. I will also get in dark pools.

I just made it a challenge. I'm sure it's much more of an intense fear for you, so please don't think I am comparing at all, but you could just try to challenge yourself just for kicks.

Thats basically all they would do for you in therapy lol
