I feel awful at the moment.
I had intended to go to bed very early because I was tired, but ended up pulling an all nighter to salvage some very important account information that I had foolishly kept on a single SD card without backup. The card refused to open - and that was the end of it.
Luckily I use LastPass, which saves your passwords and logs you in automatically when you arrive on a webiste. But the thing was that the password to LastPass was also on the SD card.
Hours and hours later I've finally managed to reset the LastPass password and as of right now I have access to all passwords I had saved there. Which is most of them, excluding some older accounts for games/website that I no longer use. It'll have to do.
Now I just need to recover the software registration/purchase codes that were also on the SD card, and after that I can finally take a nap.
What an ordeal.
