Addicted to training. Should I be worried?

So I’ve been training for just over 3 months. I started by going 5-6 days a week and I have kept up that intensity more or less, even doing 7 days sometimes (rarely though as work doesn’t allow it)

On the days I can’t train I get frustrated and even when I’m at work I constantly yearn to be in class. I know why this is (seretonin, dopamine etc) but I’m just wondering, should I be worried about this?
