New Motivation and embarrassment

So for the past almost month I have worked out almost every day and have been feeling totally awesome! I've been wanting something for the past 4 years that I haven't quite been able to afford which was a Treadmill. I can't bring myself to go outside and go for a walk around the neighborhood to try to burn those few extra calories, I don't know why I'm embarrassed. I guess its because of the way I look and the looks I tell myself that people will give me. Although I am over weight by about 45 pounds and everyone says that I don't look that big, I still worry and still feel embarrassed. Anytime I would work out I have to make sure that I am at home alone and do a workout video online. I've been hinting around for four years to my husband that I would love to have a treadmill. That way I can go walking when I want to in the comfort of my own home and not feel as if everyone eye in the world is watching me. After many failed attempts of trying to get one because of lack of money or the treadmill was messed up somehow from someone trying to sell it I started giving up on having a treadmill of my own. Finally today my husband surprised me with a treadmill. One that tells me how many calories I've burned, how long I have walked, how many miles I've walked and how fast I'm walking. I tried it out for the first time this afternoon and I am in love. I no longer have to feel embarrassed because of my weight. I can go for a walk anytime I want. I have found my newest motivation and its time to turn my spare bedroom into my exercise room. I'm really considering trying to get a stationary bike next.
