Will Helium mess up my lungs for a long time?

So earlier today my little brother and i both inhaled 2 balloons of helium then about an hour and a half later we tried to run 2 miles. I have never had such a hard time breathing in my life. I can normally run a pretty good distance before having to walk but i couldn’t even go 20 feet this time. I kind of figured it was because of the helium, anyway, am i going to be like this 2maro still or will it go away soon?
