Apple music

I have been paying for Apple Music for years and all of a sudden it knocked me off and is only showing minimal music that was downloaded years ago when I first got it. I signed out and back in but it helped nothing. The only thing I can think is I somehow had a different Apple ID years ago and maybe it defaulted somehow to that? I went to settings and put in all my current info but it brought nothing up. I even tried to log into my old Apple ID but it kept saying it was wrong. I do not know what to do.
