That would be great except I already made a character and it's not a cleric. So in other words too bad so sad, you F'd up now you have to start all over? well that sucks ass.
You're literally like 2 minutes into the game when you get to Shadowheart, so I fail to see where the problem is?
And again, you don't need a cleric to play this game? So how have you F'd up?
There is nothing at all stopping you from continuing to play the game.
If you think this is an F up, then just wait until you start failing rolls and making the wrong decisions in all the rest of the game.
