First of all, rain coaster, thank you for taking the time just to be rude and totally unhelpful, I'm sure you feel very smart. However, just for your information, the context of how I ended up in this conundrum is more complex. I made a fresh blog but didn't realize I could actually change the URL of my current blog without first deleting the fresh one. Therein lies my mistake. I assumed that since URL of my other blogs could be changed without permanence then deleting them altogether wouldn't necessarily be permanent.
Thanks to those who did answer my question.
