Panic attack

So I went to bed last night around 1030. My boyfriend is off work this week so he stayed up. I got into bed and all the sudden my heart started racing so bad, I had trouble breathing and got real dizzy. I barely slept last night. And now I am at work for the next 9 hours. Please let today go by fast. I have no idea what brought on the panic attack last night but even now I still feel off. Any suggestions?
