Help!!!

I believe that I am a compulsive lyer. I have lied to my husband so many times I have lost count. I have a four year old daughter and I don't want her to grow up like this. I think I tell lies to get attention and approval. When I was a teenager I would find a pair of shoes on sale for $5 and buy them then tell everyone I actually got them for $3 just to make myself look that much better. Since I've been married I have lied to my husband about being pregnant, about paying bills about our finances. I love him and I want to stop hurting him and be a better example for my daughter. Because I do this I also feel inferior to him which doesn't help. I was just wondering from those of you who have been hurt by someone like me, what could I do to make it better, because my words have lost credibility and my actions say I don't care. Thank you in advance for your advice.
