hey mona, there are tons of 'walk-to-run' style classes in my area where you go and sign up. they give you exact steps and training in a group of folks similar to you. my wife (who was 100# overweight) did this class and was able to finish a 5k race after 10 weeks. went with her, she did great, it was painful, but your mind is the biggest obstacle.
You can do this, if anything a treadmill at a gym with a schedule of how long to run - walk is a great way to do it too if you can't find a clinic around you.
YOU CAN DO THIS!!!
Found a similar program on 'runnersworld' under the training section, getting started - the 8-week beginner's program.
