Like many other things, weight loss is one step at a time and finding what works for you. If something works, do it more. If it doesn't work, stop doing it.
One thing you may want to look into is the Couch to 5K program http://www.coolrunning.com/engine/2/2_3/
. A number of us on the site have done it; it is a nine-week program that purports to take you from couch potato to being able to run a 5K (3.1 miles). But the flexibility is there to repeat weeks or take it slower. When you are ready to progress, move on to the next week. It is a beginner's program. It incorporates brief periods of running into mostly walking at first, then it changes the proportions over time. It is structured but it is completely individual, so that may be helpful for you.
Also, keep in mind that losing at a reasonable pace (~2 lbs per week) is the safest and most sustainable way to lose. Trying to rush it tends to backfire.
And baby steps are better than standing still, or going backwards. Give yourself a break...you're doing something about it, and for now, that's fine.
