A wrench in my running wheel.

A wrench has been thrown in my half marathon training. Things were going along swimmingly. I am/was getting a little impatient with how slow time was moving, and just wanted it to get here, so I could do it and go back to my cardio/lifting routine. Anyways. On Friday, I started to have some discomfort in my chest, near my heart. Long story short, I went to the ER on Saturday night, and they ran all sorts of tests; EKG, blood clot, chest xrays, thyroids, etc. Nothing showed up except a slight palpitation, but nothing that concerned the doctor. The resident told me it was ok to run, but the other doctor who I saw said to take it easy. Which is hard to do with like barely three weeks left before the race. Even now, almost a week after it started, I'm still feeling the pressure. It makes me nervous. I don't know what I should do about this race. I'll have wasted a lot of money after registering and not doing it. And also be super disappointed that I put in all that work, and told SO many people I was doing it, just to not. However, I don't want to risk my well-being by pushing myself to do something I shouldn't, even though the doctors said all my tests came out fine. I just don't like not knowing what is going on. And I've never had any real health problems. The only major things was a slight case of mono my freshmen year of high school and my horrible nose bleeds as a child. So I'm not quite sure how to cope with all this. The doctors also mentioned to me that it's probably anxiety. Which I've known for a while now is something I have. I just wasn't aware chest pains or whatever could last thing long with anxiety. I always thought it was something that was over within 20 minutes or so. The anxiety is another battle I'm clearly losing, that's another thing I have to get taken care of. Ugh. So basically I don't know what to do or how to handle this. I'd just go to the doctor until somebody figured something out to make it stop, but I don't have insurance right now therefore making all this very expensive :/ Just please pray that I figure this out soon or that it'll just go away. And that I can convince myself that not racing won't be a blow to my credibility and that my health is more important than a stupid race. Le Sigh.
