I’m really stressed! Does she hate me?

Ok so I have a friend from school. We haven’t hung outside of school yet because it’s a new friendship, and we are not in the same friend group! But anyway I still like her. I know she does get anxiety and things like that. We have each other’s number and text sometimes about things and she has said she is always here to listen.

Anyway over the holidays on the first week I asked her if she wanted to catch up over it. She texted back “I am busy in the first week but probably in the second week. But I will let you know ☺️” I said “sure, sounds good.” But she never got back to me. To be fair. I actually didn’t realise until tonight I have been busy doing work experience, getting a job, a hang out with friends, mainly resting though because I commute and hour there and back so I feel so exhausted! Anyway but I suddenly realised and now I’m worried what if she hates me?! What do you think?
