I won't be able to help you recovering your password, but if I may suggest: Type the password a few times so that you don't forget it, that will help remember it.
It may help to write it down and type it a few times to remember it, then do whatever you feel safe with the paper to destroy it =p
Another tip: Make a password that will be easy for you to remember but hard for other to guess. Example:
1- Take a song you like and that nobody will be able to guess which.
2- Now take part of it's lyrics and transform them in a password. So, if the lyrics are "You'll take my life but I'll take yours too", take every initial letter and make it "ytmlbityt", and if you're more confident make it with symbols, upper case and numbers, so it would look like "ytM1l%b=iw[ty2". This is very useful if you want to create a strong password that is easy to remember.
I use the method above to create my encryption passwords. All of them are 64 characters long randomly generated using the method I described, but with almost no key repetition. So, they look like "_xJ3Bo9<A1.lcv7>0pPHy5Va,jbC2Z(iOp+4MXK" but 64 characters long. It ensures that no brute-force attack will be successfull even if all the computational power was put into brute-forcing it.
