Help Help Help!!!

I am slowly learning, but I am not very good at all this blogger technical stuff... Can any one help? 

I ruined my navigation bar, which wasn't very good in the first place, and I also no longer have an about me section and I can't figure out for the life of me how to get it back! :( 

Any help would be greatly appreciated! 

Please excuse the lack of posting...my little one is trying to cut eye teeth and they have pretty much put our entire week at a stand still! I am, however enjoying the extra cuddle time with my baby!
