Help ...i am scared

I have recently been issued a learner lisence and have been learning to drive since last 3 weeks, so today at midnight i tried to give a shot to try to run my car by my own for the first time and was successfully driving but while turning at a blind turn of a narrow gali there was a swift (cab) whose front bumper got crashed with by side door and the bumper came loose also my cars driver side door is not opening now due to the dent. The car is my fathers its a 2007 alto car. Now in that situation since it as midnight there was no one nearby and i somehow got out of the situation and drove home and now i am scared what will happen, i am also feeling guilty that another person's car bumper got loose because of me and that my cars door is also not opening. That car was parked not far away from home and if someone saw even remotely they will surely come knocking at my door. Now i am scared that what will happen tomorrow. Pls tell how much is the approx cost of repairing my cars dent ( the dent is on the driver side bonnet and driver side door such that the door is not opening now) and the other car(whose bumper got loose) and if i can claim 3rd party insurance for this? And what is it's procedure, i have never claimed it before.

Edit - The matter is resolved now, we went and had a discussion with the driver of the vehicle concerned and repaired it at a nearby mechanic shop. Thanks for your responses 😊.
