This might have been said before but my advice is simple. When you're alone, have the house to yourself for awhile; walk around naked. It feels odd at first, but doing silly little tasks like vacuuming naked helps you to feel comfortable in your own skin. It's like wearing an outfit that makes you feel drop dead gorgeous, only you get to have it on all the time!! I don't know if it's necessarily the answer to your problem, but it'll certainly make you feel sexy 24/7.
