The human memory tends to be very associative.
You may find that it will help to think about other things that were going on in your life when you created the original wallet more than a year ago. What time of year did you create it? Was it near a holiday? Was it during a particular season? What event caused you to try installing a wallet back then? Did you ever try receiving or sending any bitcoins with that wallet? If so, where from and where to? Thinking about sights, sounds, smells, and experiences that happened near the same time as the creation of the wallet can bring back associations in your memory that will help you realize more about the password you might have chosen.
For $100 000, I'd even consider talking to a well respected and experienced hypno-therapist. Even if they can't use hypnotism to bring back the memory of creating the password, they might at least be able to help you think calmly about it so that anxiety and panic don't cloud your memory.
Believe me I was trying all that, despite the hypno therapist. The money in BTC is not lost, still on the wallet, nice and safe, so safe that actually even I cannot reach them now. My password didn't make sense, its nothing what you could memorize, its just pieces of passwords and nonsenses. And its difficult to make sense in nonsense.
