I recently found the self help blog A BLOG ABOUT LOVE, which is run by Mara and her husband Danny. A few years ago, Mara went through a very bad time; she had infertility and marriage problems and then her marriage broke down altogether. This left her in a very bad place. But she began working on herself and trying to feel better and her life completely transformed. She became happier and everything in her life improved. She was then introduced to Danny by a friend. They started emailing each other, fell in love and got married in May 2010. :) A BLOG ABOUT LOVE is their joint project where they share their love story and the things they've learned about becoming whole, happy, fulfilled people.
I really recommend these posts on vulnerability and connecting more with others. That's something that I find hard to do. The three steps are Own Your Worth, Let Go of Fear and Love for the Sake of Loving.

There's also lots more helpful stuff on the site, on the subjects of self worth, being happy and relationships.
