Is my Asthma back?

I've been diagnosed with Asthma in 2010 when I was about 8 or 9. Everyone said I breathe heavily and my mom told me it goes away forever and I looked it up and it doesn't and people asked me if I was okay and I said yeah. And at school it was hurting to breathe one day. But I remembered I had Asthma. Could it have come back?
