I made a bad dua.. and now its been accepted

[Jasir786]

I made a bad dua when i was in an emotional state. My ex wife and I were apart. So i begged allah to put us back together or for us to be apart... even if it meant at any cost. Death or jahannam, but i didnt MEAN IT. I said ill ask for forgiveness fromyou later allah. But i realize how bad it was later. Because later that night, it was shown to me that i made a bad dua and now its been decreed. now what do i do? how does one take back a dua they regret?
