sorry my friend. Tough luck.
Like any other passwords, DONT LOSE THEM in the first place!!!!!!
YOUR KEYS. YOUR COINS; NOT YOUR KEYS, NOT YOUR COINS
due to the decentralized nature of the blockchain, there is no one single entity you can look to when things went wrong. Steemit.com does not store your password, no one will have your password unless you give them or it was hacked from you.
There is however a recovery procedure as @sheikhsayem described, but that is only in the case of an account hack (where your password got changed by the hacker) or if you opt to a 3rd party service that stores your password for you (highly dangerous, dont do that).
What people need to know about Steem is that it's not just a writing platform that gives you money. It's literally a bank on your laptop and phone, you have the freedom to do whatever you want with your cash and have to bear the responsibility that comes with the freedom. a Steem account is WAY more powerful than most average users realise.
Steemit made it very clear that you are responsible to your own password, you need to make sure to make multiple backups including offline and encrypted files on the cloud in somewhere safe.
unlike banks, with steemit. You are entirely responsible with your account. because unless you explicitly allows it, no one else can touch your account.
