Iphone 5s blue screen of death

So yesterday my iphone 5s that was brand new at Christmas was being very glitchy. It was freezing and then I did a hard shut down (hold the home and power buttons for 10 seconds) at now when i try to turn it back on the the white screen with the black apple logo shows up then the white wheel show up the phone wont load up and the whit wheel just keeps on spining until it overheats and then i get the blue screen of the and it restarts itself and repeats the whole thing again. So any answers will help me. Thank you very much
