Fuck damnit, I had 100 waves somewhere on my pc but i lost my fucking password, and now its goneeeee ah 
If you are talking only about the password, not about the seed phrase. You can restore your account using the Seed and using any other login and password.
Check tutorial - https://wavestalk.org/waves-lite-client/waves-lite-client-tutorial/ (How to import account)
So i guess there is no possibility to recover somehow passphrase? I lost my 2 wallets: 3PM6p1hQsrRU2m6hzHvNYWjFcw69yfnHUeY ; 3P846xT218qiYk6itXEKwDfqgEC683whKqP
The Seed phrase - No. Lite Client password - Yes. Just import new account with your Seed phrase.
