@Crazy Hitch - I know you said you are self-conscious to walk for exercise outside. Have you thought of doing some exercise indoors? I do pilates, and you don't need any equipment really, not even a mat if you have carpeting. There is a fantastic free YouTube series called "Move with Nicole". There is a playlist of 10 of her beginner videos, but some are much harder than pure beginner as I still struggle with them, but 2 of her beginner videos are a great place to start. The easiest is her Absolute Beginner Pilates video:

And once that gets a little easier the next one (this one has a really good arms workout) is:

The videos are absolutely free and even if you suck at coordination (as I do!) you can still follow along fairly easily. True, you won't burn as many calories as walking, but you will burn some, and pilates is fantastic for toning.
Another thought, you could buy some light dumbbells, 2 or 5 lb. if you don't have any. There are a lot of arm exercises you can do with dumbbells, plenty of vidoes online regarding that. Just a thought. If you can get moving with exercise, you will begin to speed up your metabolism as well which really helps with weight loss.
