Why did I lose all of my levels? I am back to level 1

Hello .... I am new to this community.. Have been playing candy crush for almost four years now and for some reason my levels were lost and I am back to level one.  I was somewhere in the 1300s....don’t remember exactly. The only thing I did different yesterday morning was add my email to my account.. don’t no why I never did it before but ended up doing it yesterday. I don’t have a Facebook so I don’t use that..Does anyone no how I can get it back?  Thanks for reading this
