Everytime I fall a little bit harder

I am two weeks in to a 4-6 week ban on running. Not self imposed (I'm not crazy), but I'm actually following the doctor's advice- this time. Back at the beginning of February I started to have shin splints. I took a couple of days off and figured they'd go away. Then I ran a race and busted out two of the fastest miles, I've ever run. Hey six minute mile! After the race, I eased up on the distance and began to focus on speed work. I'm not sure if that's where I went wrong. The shin splints returned with a vengeance. Suddenly any downhill running or flat stretches were accompanied by an aching pain that simultaneously felt like my right shin was on fire. I'd stop, stretch it out and keep running. But that was merely a band aid. I figured, maybe the street that I ran on was too hard of a surface. So I hit the trails. That seemed to solve the problem for a minute.
One day on the trail as I crested the top of a mile long climb I thought "I didn't hurt at all." Sad when the pain is consistent enough that you recognize its absence. And as I started the rolling descent those words would blow up in my face. The pain came back and no amount of stretching helped. I hobbled all the way down. And as I got into my car I realized "Shit. Something's wrong."
The next day at the doctor's office I told her everything and as I heard the words coming out of my mouth I started kicking myself. Had I really just kept running with that pain? Why hadn't I made more of an effort to take a break and let my body heal? Could I have prevented this? She poked, prodded and stretched my leg and then said, "It sounds like a stress fracture." I didn't even know what that was. As she outlined what it was she also mentioned that I wouldn't be able to run for AT LEAST 4-6 weeks. And that's when I lost it. I cried and all I could think was that I wanted my mom there. I'm laughing as I write that. Seriously, I'm such a drama-rama. You would have thought that she said I needed my leg amputated. But all I could think was all that hard work, all that time, all that sweat- for nothing. It was all gone. The idea of having to start over really sucked. When I went home I put my running shoes in the closet, figuring it would be easier than looking at them everyday. I guess it's true, you don't know what you've got til it's gone.
Fast forward: And after a bone scan, which required me to drink some weird liquid which made me ever so slightly radioactive and required copious amounts of water (I think I spent the majority of my morning peeing) it turns out that I don't have a stress fracture. Score! But apparently I'm working my way into a stress fracture and have to go to physical therapy and still take time off- treating it like a stress fracture. Lame!
Went to PT yesterday. The first thing I said was, "I don't understand, I thought I was doing everything right. I increased my mileage incrementally. I took the appropriate rest days. What gives?" Remember how I wasn't happy with my shoes? Turns out I've totally changed the mechanics of how I run on my right foot to accommodate my shoe. Apparently the front of my leg was absorbing most of the stress and my calf muscle was underdeveloped. Blew my mind! I mean, I had just written about not being happy with my shoes. I'd even noted that they sometimes hurt my foot. Weird how I just kept thinking I still needed to break them in. The good news is that I can do low impact exercise and I can get back to running in a couple of weeks. I'm thinking about making a chain to count down the days. Not-so-bad news: I have to ease back in and can't pick up where I left off. I'll take it. The doctor also recommended that I increase my protein and calcium. I'm supposed to really be cross training, giving my legs a break from just running.
I've realized that this is my third injury in three years- hip flexor, bruised heel bone and now this. Hoping this is the end of the road for these things because I really do love running.
