Everything is just whazzing around and messing with your head - but thats OK and I hope that by being able to come here and share your thoughts and pain that it can ease things a little for you
Hang in there, go with the emotions, try not to beat yourself up about how you might or might not be feeling.............life will return to some sort of normality, but it will be a new normality........and thats what you are fighting with at the moment.
Take care
