Oops I boiled my starter

Hi everyone, 

I'm new to this website and hope to learn some new things about bread. 

This morning I was incredibly tired (newborn baby in the house), and while I was feeding my 5th version of my starter I accidentally poured freshly boiled water on it. 

I usually pour the water from the kettle, when it's cold, but this morning I wasn't thinking straight, and then it happened. I quickly poured out the water and added some cold one, but the jar felt hot anyway. 

I'm at day 3 of my sourdough starter, my question is, did I kill it? Should I just trash it all away and start over? 

Thanks in advance.
