Beating : A story about love...?

Update 4(Oct. 16 9:12 AM)

Hey, I just got off the phone with the doctor. Apparently there will be no openings in the schedule until next Tuesday. How can this guy be booked up for over a week!? I thought about trying another practice but my family has used this one for a long time so there is kind of a weird loyalty thing going on there. Anyway they asked when I called them what the problem seemed to be. I told them I could hear my heart beating all the time but that I had checked my own pulse and it was under 100 bpm. I then had to sit through the expected questionnaire whenever someone mentions heart trouble. "Do you feel an pressure in your chest? Do you feel dizzy or nauseous? " and so on. I tried my best to keep calm but by the time I hung up the phone I knew there was a slight hint of fed up in my voice.
The beating sound has behaved pretty much the same since I last wrote. It thumps and thuds and chugs away in my chest, not for one second letting me ignore it or tune it out. If it was not getting progressively louder before it certainly is now. I can have to turn the volume up almost twice as much as normal on my headphones now to even be able to hear any videos I am watching. I can somehow still hear people talking but they are all slightly muffled by the beating of my heart. My date with Jane is tomorrow evening. I find myself looking desperately forward to the moment I will see her again. Even though she seems to have in some way triggered this problem she is also the only thing that has mitigated it at all since it started. Also maybe this time I will actually get a chance to bring it up to her, I am starting to think that might not be the best idea though. She might think I am trying to pull some sort of cheap line on her and I don't want that to happen. Jane is the kind of girl you only get a chance at once in a life time if ever. I don't want to blow it by bringing up weird stuff.
I have to get started on school so I guess that is all for now. Thanks to all who have sent their sympathies and advice.
