If you did do a screen shot it might be in your computer somewhere. I checked your wallet and it doesn't seem like you will lose much. If you can't find it, I would make another account as fast as possible. It may take awhile to get in. Once in, write down your password multiple times on paper and store it in your different safe places. It is in the white paper that there is no way to get the password from them once a password is lost. I would not post too much anymore on this account as if you did lose the password for sure you lose it's monetary value.
