Rebecca,

I'm sorry the letter hit you hard, it doesn't help that you are sick too. I think you should try to put the letter and contents out of your mind for now, concentrate on feeling better physically before you try to tackle the mental working it out side of things. Do you have a counsellor at school you can confide in? It may help you work out some of the confusing things about your degree etc.. I wish you well. feel better soon and most importantly take care of yourself.
