Should I go to hospital?

So my Drs office is closed today and tomorrow.. I haven't been feeling very good lately.. My heart starts beating really fast and I feel super exhausted instantly and also my sight gets really bad.. But it usually goes away after a bit. Well it's been an hour this morning and I still don't feel good.. I almost feel confused.. I tried being up for a bit but exhaustion takes over and I just want to lay down.. But even laying down feels exhausting.. Has this happened to anyone?
