An option could also be to go through old computers, mobile phones and other devices that you may have used to handle cryptocurrencies. Sometimes the wallet may be stored locally on a device that you no longer use.
Search through old documents on your computer to see if you may have written down the back-up key needed to recreate your wallet. It can also be good to search among old documents and papers for more information.
If you can't find your old wallet using the previous tips, consider contacting the customer support of the crypto services you used, if you know which one. They can give you guidance and help to find your wallet
