<human>: Can you condense the text into a few key points?

I ran throughout high school and was in very good shape and was very thin. I stopped for a year and a half after and just started back up these past few months. I suffered from AWFUL shin splints then and I get them now as well, but I'm fairly used to them. However, I am heavier now and out of shape, but I'm used to being able to just get up and run, so I push myself too hard, thus causing me to spend the past 4 weeks with a stress fracture in my foot. So, I need some advice to help get back into running gradually on a plan that works well. (I have used C25K, but I still find myself running fast because I am built that way.)
<bot>: Need help getting back into running without pushing myself too hard (which I did and am just now out of a boot for a stress fracture in my foot). Advice?
