My account not showing up

So I had a account of 118 ovr (YKLegends) which I have been using for 2 years, and I decided to make another just for fun, after playing on the second account for a while, I tried to login to my main account (YKLegends) it just doesn't show up, and also I have linked my main account and my second account to my gmail. Please help me, or I weeks have to restart everything from scratch or just have to quit.
