I lost many of my blog sites i watch..i am sick about it!!

When i redid my page i thought i had saved everything the same as before....i didnt notice until today that my blog sites i read were gone!! I hadn't saved them on my dashboard because i wasn't a followed just a secret grazer. Such a big mistake. I had some photographers on there that were amazing and now i will probably never find their site again! I found many of them from memory and added them the proper way so i can't lose them again but i want all of them back. I am so sick from this!! How sad!!
