Is it weird that she message me back?

in my last year of highschool one of my female teacher i had a crush on her.

over the years i sent her messages on facebook she never responded one time i was drunk & lonely at told her about the crush i had on her that was years ago that i sent that message.

i sent her a message a few weeks ago & just said this its chris my sincere apologies if i wrote you too much. I'm going through a very difficult time in my life. just wanted to be honest.

she wrote me back today saying Hey Chris I hope everything is ok i'm just in shock that she wrote me back.

Is it weird that she message me back?
