I had the same experience a few years back and luckily the blog survived when I checked around 1 and a half years later.
To retrieve that blog, all you need to do is:
Log in to your Google account with which you have created that blog. In my case it was a different account from the present one.
Then in a separate tab, type blogger.com. Make sure you have signed out of the current google account, if the concerned one was created with a different account.
If your blog is there, then you would get to see the dashboard instantly. Once you access it, you can make whatever changes you want to make. Preferably add as much more content you can, polish the exiting ones, post them on social media pages and you are back on track.
All the best.
