I just need to understand..

Abbie

Hi. Iā€™m 14, and last year my half sister went to rehab for severe anorexia. I havenā€™t spoken to her in over a year now, and sheā€™s still in rehab. I just dont understand anything. I went to therapy and they told me I was ā€˜grievingā€™ her, even though she isnā€™t dead. I just need to understand the mindset, itā€™s killing me knowing I could have stopped it, I knew the signs and we had all noticed but none of us did anything. I just donā€™t know what to do.

This is a picture of us about a year before she went to rehab, she turned 16 just after she went in, and I was 14.
