A girl I have known of for roughly 6 years has just ditched me cause in her words "your too ill" WTH!!!

I sent her a message this morning and it took her 2 hours to come up with this answer. She read it straight away. Then took 2 hours. Who does this. This is after may I add she messaged me at 3am cause I didn't give her an answer she was looking for she said I was in a bad mood. It was now 4am I was shattered. My message to her was we need a break.... then she blocks me on fb and fb messenger. Well I'm not being funny but f you. I'm raging as I have done nothing wrong.

My sister is glad as she has always thought the girl in question was a bad influence on me and that she made my paranoia worse
