How to deal with anxiety/mini panic attacks?

Last night at 3 am I had at least 10 of these when I was trying to sleep, I'd close my eyes for 2 minutes then all a sudden my heart starts beating really fast and I can't breathe then I'd have to get up and breathe hard.. It JUST now happened to me starting last night, why? And how to deal with this because honestly I didn't know what to exppect last inght I didn't know what could happen, etc. It was a scary moment for me.
