Lost all bookmarked blogs

In my post So much to read, I told you all that whenever I find a good or an interesting blog, I bookmark it so that I can read it later. Whenever I get the time I read those saved blogs. I had bookmarked many blogs to read later. They were more than 100 as I keep bookmarking blogs, but today, I lost all the bookmarked blogs which were saved in the WordPress app. What happened was that I was trying to find a way to make appear all my published posts in my blog feed as all my published posts were not showing up in my blog feed, so I logged out from the app and cleared all the cache of the WordPress app. When I logged in back, I found that all the bookmarked posts have disappeared. I am upset as I was so keen to read all those blogs. Why do I keep doing stupid things to annoy myself?

I do stupid things.
