Don’t worry I think she’s ok! A lot of times artsiest don’t post! Yes I understand your worried but this happens with everyone! I used to post everyday but now I post on hoildays and just days I feel like it! She might be busy or making a big project! Trust me don’t worry this happens with everyone!
