More advise please.

So first off I just want to tell you guys how awesome you are. I love this community and everyone in it!

Ok so, tonight my family and I attended my sisters dance recital and it was amazing!! My sister and all the rest of her hip-hop group were so good it brought me to tears. There were also many other groups there performing almost all styles of dance and it got me very excited. So exited, in fact, that I'm thinking about taking up tap dancing. The only problem is that I have this huge fear..........well self confidence issue actually. See I used to be really fat but even since I lost all my weight I'm still not comfortable with my body. I still see myself as huge and my attitude reflects that. I'm afraid to be myself around people and thats what keeps me from doing things. I really want to learn tap though so does LGBTeens have any advise for me?

EDIT: Thank you for the advise. I have decided to take both tap and jazz and I could not be more excited!!!
