I lost access to my e-mail and I can't log into my Steam account. How can I regain access?

When I was trying to log into my Steam account, Steam wanted me to input the Steam Guard Code, so I checked my phone and there was no code so I tried to change my password and try again, I did it and the password didn't even work, but the last one did, then I tried to disable Steam Guard Verification, after that I was logged out of Steam on both my phone and pc, so I tried to log back and Steam wanted me to input a verification code sent to me via my gmail, but my gmail account has been disabled a month ago and I can't get it back so... I have no idea what can I do now to get my Steam Account back and I'm really worried because I spent a lot of money on it.

Solution 1:

Ok so I got my account back because I reminded myself that I had my phone number attached to it and it made it possible for me to change my Steam e-mail. Thanks for maybe a little but still some help. I hope anyone who has similar problems finds it useful.
