I love to run although haven't been doing as much of it lately. Just a couple months ago, I was running (2) 5ks a week and it really does make you feel accomplished.
Good luck to you. Running is about pushing your limits - 9 times out of 10 when you feel like you have to stop, you really don't. I feel like I have to stop at mile 2.5 almost every time but somehow I manage to make it.
