Al you can do right no V is take it one day at a time .Don't expect anything from your self right now,let the tears flow.Howeveer with that said you must eat and sleep.Maybe you could ask the doctor for some meds to help you with the sleeping part or even try simply sleep made by tylenol.It stops all the thoughts and lets you sleep,you won't feel drugged by them.Once you eat and sleep youe emotions should respond a bit.
Take care of yourself,yt needs ya.
