Go.
This is happening with my roommate. It started out as migraines, then it turned into her passing out at work. The ER said it was Malaise the first two times she went to the ER two years ago. Around the 4th time she saw a doctor it was seizures endued by stress. Flash forward to today, the last time she passed out at work she stopped breathing. She's still alive. But i worry for the day when I wake up and she doesn't.

Do what Coda says before it becomes even more serious. If they don't think its anything ask them to do heart test, see if your valves are working or if you have any other problems.
