I broke into running very slowly. I walked for 6 months before I even attempted any running. I worked up to 3-7 miles a day walking. Then I would run for 30 seconds and see how I felt. Eventually, I could run for a minute. Then I could run through a song or two on my headphones. Every little success pushed me to stick with it.
In November, I decided to buy proper running shoes and commit to a program. My program is 3-4 days a week, and never on consecutive days. After 2 months, I can run 5 miles on my long run! Now, I'm not saying this is how you should approach your program, but I'm just saying you can accomplish a lot in a short space of time without overtraining and burning yourself out.
Good luck!
