Back before I was even a teen, I had an email account that is connected to my old myspace, etc.

I can't remember the password for this account, and when I went into the updated Hotmail account I made for when I was in high school, there are now no longer any received or sent items (there is actually a completely empty email account).

I went into this second old email account because it was set up for me to have all of my emails from the original account forwarded to it. I am currently trying to delete old social media profiles from when I was younger and they are all connected to this very old email.

How do I go about getting back into this old email, because I am almost certain it has had security issues and has been hacked in the past, but it is where all my old social media delete requests are being forwarded to?
