I can't imagine what it must be like to feel that you have lost so much in a short period of time. I am glad that you wrote Cary and that he published your letter so that you can get advice from him and support from readers - many of whom have had experiences somewhat similar to yours. You are not the only one, but in some ways you are alone. Yo must be your own best friend, your own advocate. You must look after yourself and try to not let this become the main and only thing in your life. Eventually you will come out if this stronger, braver, more empathetic, more understanding, more mature - you will be a wise person and you will be OK. I hope your sister will come around - she is probably scared - but she may not. Keep looking around you and forward, there are still good things out there.
Take care.
