How should I keep this conversation going with her?

: How should I keep this conversation going with her?
I have a big crush on this girl named Susie. We haven’t talked in person yet or said Hello… But anyway, like 2 weeks ago we had a conversation (technically our first one) and we were talking; some time during that I replied to her but she didn’t reply back. So like a week later, I sent her a message “Hey Susie, how was your three day weekend?”…, and she didn’t reply. But then she did a Facebook thing like “Lms for tbh in your inbox” and she sent me “To be honest– Youre a cool person. 😀 “.
And from there, we had a conversation (which is continuing).

(in the conversation) Me and  Susie started talking about how she played sports and what we do in gym and stuff. 
And the last message she sent me said something like “Oh cool. And I hurt my wrist because I was going for a layup in practice and Coach Williams hit the ball hard”. 

I’m stuck in the conversation and I don’t know what to say to keep the conversation going. I know I’ma say feel better but what else should I say?

* I know what I said first in this question may not seem like she’s interested in me, but as the answers to previous questions were, Susie may have a crush on me,… And even my best friend says she thinks Susie does.

I’m assuming you are in the high school age range.

Go ahead and share your own “like” experience to what she says to validate what she is trying to convey about herself.

If she is trying to be funny, say “that’s hillarious…”

If you want to be interesting… be interested.
