Stuck in Water

[Moonvibes]

Ok I'm not a brand new player, but it has been awhile since I've played. How do I get out of the water in Halas??

I tried getting onto the raft but fell into the water. I tried getting back up with no luck, and then I swam to the other side but still couldn't get up over there either.

I was in first person mode, looked up, tried hitting page up a few times. Made sure to turn off crouch a few times just to make sure it wasn't on.

I'm so confused lol
