I was lucky it finally worked out and I access my coins again, I will make I sure I have multiple backups of my seed in the future..
Make sure to store those backups in a secure place because as you can see anybody who gets their hand on your seed phrase can recover your wallet and take your coins. Therefore you should know that storing it digitally is the least safe. A physical backup (write it down and keep it in a place where nobody can access) is a lot better.
