Ok so now i know the cause - Rallakias you were right. Its the most stupid thing in the world...The parking lights were left on (blinking) by accident since i was in rush to catch the bus, so after 8hrs or someth the battery simply ran out. I jump-started it using the cables and then took it for 35-40min drive to charge the battery a bit. I hope that will be enough... *** everyone for yr comments
