Help me find this old video/song

I don’t know if I’ve imagined this but I cannot find it on any of Lizzy’s socials. She had a song with another person, I think it was another girl at the piano. The lyrics go something like - is this what normal people do? Don’t know if it’s right but it keeps me up at night just thinking about you. But I see in my dreams. How do I know? ……

There’s a few lines in between then it’s -

And it feels like spring when he kissed me. Feels like summer when I fell in love. Feels like fall…

I can’t remember more. I had it saved but I think it’s been deleted and I haven’t thought about it in a long time.
