Dear House,
While incomplete right BBB is common, that's only true if there is no underlying heart disease. If you have heart disease, you can get your exact symptoms. Therefore you should visit a cardiologist specialist, tell him your symptoms, and let them do a complete workup on you.
I also think you may be having migraines, the "auras" they talk about sound similar to your condition. There are medications for those, that help with varying degrees of success.
And I wonder, since you work out, perhaps there is something you're taking for body building that is doing this to you. Sometimes something perfectly okay to consume, like green tea, for example, will make your heart jump all over the place and drive you nuts. So, review all that and preferably don't take anything. Also, think about what else was going on back in August that could have set this in motion.
If all that is ruled out, then your symptoms also point to a mental problem, everything from some kind of psychosis, to ordinary panic disorder, both treatable conditions. That's when you go to a psychiatrist, so they can figure out what your mental situation is and treat you with medication and maybe psychotherapy.
I think you should begin to keep records of what your heart is doing. Check your pulse several times a day, especially when you get that whoozy swimming feeling, and write the number down on a little notebook you keep with you, including the time and date. Your pulse should not go over 100 regularly. Also check your blood pressure as often as you can. Which is every time you go to the doctor, ask them what your pressure is, and write that down, including the date. It should not go over 120/80 regularly. You can also go into a pharmacy that has one of those chairs with a blood pressure cuff, and pump it up and see what your BP reading is that way.
I know a couple tricks to help your heart. One is to massage between your toes on your foot, especially between the last three. You should notice that you automatically take a real deep breath, very calming experience. Another thing you should do is, every time you get that wierd feeling, do a deep-breathing technique, becuz it slows the heart, which is to breathe to a count of ten, very slowly and deeply on each count. You won't get to ten, becuz your heart rate will slow before then and you'll "get a grip."
By the way, I've been where you are, that place you're in. I know what it's like, and it's something awful. But there is a way out. As to your fire-fighting training, keep in mind if you cannot keep up right now, that you can always go back to it later, when you feel better. See, there are always fires to be put out, and so they always need people that like to go in there and do that. You'll get there. You just have a health issue that you're dealing with now, that's all.
Most 19-year-olds don't have to worry about their physical condition. But I was just a 20-year-old when I was in a car crash that broke my back in three places, I spent a couple months in the hospital, and talk about unexpected misery at a young age! But all in the world that happened is, I got sick, and then I got well. So, welcome to the club, and you're in good company! Keep us posted, kid, you'll make it.

I know you didnt want to heat its anxiety, but its sounds just like it. Take it from a person with history of panic attacks. Its weird when it decides to come on. I had them back in 2000 and then went on medication. Then i was fine. When you think you would be stressed and have anxiety sometimes you dont its really weird. Its sounds like your having depersonalization which is very commen in anxiety. Some time you feel as if you have a brain tumor because so many weird things are going on in your body. Did any of the doctors give you something for anxiety?
p.s.s i had my eyes checked and nothings wrong with them. The nerves are completely healthy.
p.s. it gets worse if i work out. i feel extremely disoriented.
