R.J.,
You are doing great man, and keep it up. Perhaps, you can experiment with more exercises then just walking and jogging (i know i get bored with cardio very easily), so I like to switch it a lot (walking, jogging, eplitical trainer, biking, rowing), so that may motivate you to exercise.
Also, are you into sports? My friend and I play raquetball as much as we can; its fun like hell and I also sweat like hell

Also, try not to skip meals, I used to do the same thing, and it doesn't help. Even if you are not hungry, eat a little something to let your body know it had some food. For example, I had some grapes yesterday for dinner. I wasn't hungry, but I still had some so my body knew it was getting food.
Thats all I can think for now. And I highly reccommend you lift weights. I know it feels a little ackward, but once you get into a routine (and once your body stops feeling sore

), you'll really appreciate yourself more.
Thats all for now, and never give up! Remember, thats just a bigger space you have to climb up in your ladder, you are getting there!!!
edit: one more thing. If you don't want to lift weights cuz you dont' want to "bulk up" (in other words, you don't want to do it at a high intensity), then trying to do more lower intensity weights and higher reps. Not only will you be building muscle endurance, you will be also burning calories!
