2) the homepage is kind of useless. You have some text and there seeems not to be anything else around it. The real content is the blog and the link to the yahoo group. You don't need that. Make a homepage that has a) your text on the top b) the blog underneath it.
3) put some "about me" that is a quick (300-500) characters with your picture, maybe your kids and explain your story and what you do. I have been on the website a while and still i have no idea what is the issue at hand.
4) the 3) will actually link to the "donate" button. Explain that your experience and the community can help other people. your donate button is orange over brown (!!) and the text black over brown. It seems you are trying to hide it on purpose. hint: go white background and never go back.
5) your adsense banners... with those numbers you'll never see money. use that space to make a compelling story for people to donate. tell them how much. 2$ 5$ 10$
