The camel's back is broken!

I don't know where to begin, but I fear this is the end of my journey. I have been making extremely slow progress with my wiki, feeling that I will be ready with my personal best version of a digital project, not near the level of my peers but a major feat for me. All tasks have been exceedingly slow....it took me all weekend to finally figure out how to do one task to neaten it up. I persevered and conquered, or so I thought. There is a reason I have always been a slob...neatness is dangerous. While deleting my redundant materials, I managed to delete it all and cannot figure out if I can get it back. I am afraid to touch it, can't see through my tears and am starting to somaticize the stress. Is this worth it? I have climbed so far and learned so much, but then, is it possible that with the simple wrong hit of a key, I am back at square one? With all of the history settings on the wiki, I have to believe there is a way to retrieve it. I have researched desperately, reached out to my Chatzy peers and am at my wit's end. I still had more to go, but knew my direction. I really don't think I have the intestinal fortitude to start again. I need to walk away for a few minutes, try to breathe and see things clearly. I truly don't know what to do from here!!
