HELP!! URGENT

Basically I made a new gmail account on my laptop in September.

• I know the account creation date
• it has been logged in to my laptop and my laptop only for over 6 months
• since I didn’t have a password or recovery info set up - I wasn’t able to secure my account though I was logged in
• my girl friend used my laptop for an interview yesterday and somehow I’m completely logged
• it’s the email of my banks + LinkedIn + my personal blog
• been trying possible passwords but to no avail so far
• PLEASE SOMEONE HELP - my grad school application is on that email and this mishap could quite possiblly ruin my life
• I’m using the same Wi-Fi I always have
• the email acc I lost is set as a recovery email for another of my less professionally used accounts
