Forget about blockchain, get an offline Live Linux system, get
IanColeman's site (save it to an USB stick to get it on your offline system), and search until you find the private key to your address. If you found it through xpub, you know how far to search.

The wisest decision for you at the moment would be to retrieve all of your bitcoin into an environment solely controlled by you and not a 3rd party.
