I know that I might be a bit extreme here but I'd say: live with the consequences of the choices you've made.
Lots of people in this forum talk about how this game is nice because of how similar it is to DnD. Let me ask you, does your dungeon master make you reroll dices or magically roll back in time so that you can choose differently? Higly doubt that...in my opinion it''s as bad as cheating.
