My YouTube account.................

So this has nothing to do with the Apple company, but I recently have found that I can not log into my YouTube account, mine's not been hocked-up to a Gmail account in AGES (I disconnected it and made it my own channel 2 or so years ago) and I haven't had problems recently (my last issue (which was this EXACT issue) was a year ago) and I REALLY want to get back into my YouTube WITHOUT having to make a new one.......... can SOMEONE help me?!? Cuz CLEARLY YouTube can't because it just yelled at me saying that NONE of my Emails were in their system............ 😟 I've been battling with YouTube for 3 HOURS now, and I've given up, so I hope that one of you can help..........

oh and I was on the YouTube app for the iPhone (I have the 4G) during this......
