how do you change your account email to another of your emails?

While i thought this was helpful, when I went to change it, it sinabi that the email was already used sa pamamagitan ng another user. I guess I should say that I didnt know how I could put in a tanong for my problem here, so i deleted my account, then signed in to a different name. I used to be gottagofast98, then GoSonic98 because I had to change my email again. THEN i deleted that account because I wanted to change the name, because I forgot about the edit your profile. This all seems like unnecessary problems, and they are. I just should have looked better. So if there is a way to still help, I would appreciate it. I still want to change because certain of my emails are for different things. My new email is for social sites like this. So again, if there is a way to help, Id appreciate it. And I do thank you for your answer. I vote as the best so far.
