Are we still friends?

So me and this girl have been friends since year 8 and recently she's been distant. In December/January she found out I was sexually abused as a child and that's when she seemed off with me ( I was hesitant telling her in case she changed her mind of me ) and now we hardly talk unless she needs someone to go into town etc with her and her new friends are not available. We were suppose to go to the same sixth form but i failed a lot in my gcse. I have messaged her saying we need to meet up soon but she's constantly sayin she is busy.. is my friendship over with her? 😥
