Korn1, it's good. Keep it up.
But, try to walk between bursts of running instead of stopping, because you need to build up your stamina, and walking will also exercise different muscle groups while you walk.
The blisters are a problem though.
You can do the army route: Go to a chemist, get some strong stuff to basically burn out the blisters and dry them out.
You can do the insanity route: Run in them till they're sore and bleeding with all the skin worn off, and then let the wounds heal for 2 weeks, leaving you with much stronger skin as the replacement.
You can do the human route: Let your existing blisters heal and get better running shoes. Though, sometimes no shoes will solve the problem. e.g. I run in leather sandals simply because my feet sweat and will blister quickly in any closed shoe.
