Change Minecraft account email?

I wanted to play Minecraft again with friends but I couldn't log in. After a long time back and forth I saw that the email address was changed, but the password was not. So I can register again, but I would very much like to use my own email. But to do that I would have to do my security questions but for that I would have to click on a link in the current email which logically does not work. By the way, Gmail says that the email does not exist. I've owned my Minecraft Acoount for over 7 years and I don't have a transaction ID, and Mojang's support isn't exactly helpful. Maybe one of you can help me

Hey so you can go to support and then enter your exact topic, next you will then enter that you would like to reset your email, then you will be helped.

Or look best on YouTube, there are also solutions
