might have fried my arduino

I was working on a new project with 5 leds and accidently used aref instead of ground, it doesn't blink anymore. Is there any way I can check if it's completely destroyed or if I can fix it?

Is the Pin 13 LED working or it is also included in the So called Disaster?

Most probably if you do not connect the Ground the Circuit just never works because nothing can make a flow until the Ground along with +Power is applied to the circuit , so mainly everything should be alright because you are not using heavy load’s and moreover i Assume the time for which you kept the circuit on was brief (About 1-2 min’s or something like that.)
