Unfortunately, if you lose your seed phrase, you won't be able to restore your wallet.
Blockchain is a decentralized system, and there is no tech support, so in order not to lose access to your cryptocurrency savings in the future, you need to do the following steps:
Firstly, when you create a new wallet, write down a seed phrase on paper. Before you confirm the creation of the wallet, check several times to be sure the words are spelled correctly. It's better to reassure yourself.
Keep your seed phrase on a piece of paper out of reach of others.
Remember: never keep your seed phrase on your computer or send it to anyone else. These simple rules will help you save in the future.
