Struggling to add share buttons on my edublog

I have just spent about 5 hours trying to update my blog, when I thought it would be just a matter of paying to become a pro-user and then I would be able to add a few more pages and start adding some, share buttons (twitter, facebook etc) and ‘fascinating’ content. However, I have not managed to add the share buttons despite using the edublogs help videos, as well as other online videos. So I still have no new content, and I feel frustrated and digitally incompetent.
