Site under construction

I am so upset and frustrated with my blog right now. I was really happy with my blog other than I really wanted a different layout so I was trying to find one and did but when it went together, I lost all of my page elements. I am so mad. I even backed up a copy but the elements didn't save. I'll be working on it tonight but until then, it's going to have to stay the way it is. I've got to get some sleep and deal with it with a clear mind....

Does anyone have tips about how to add the really cool layouts that everyone seems to have and where do we get the layouts?
