Hi - I am sorry that you have had some bad news. You mention that you are 'eating for no reason again." - well I would venture to say that you know why you are eating - it is your way of trying to deal with the bad news. Unfortunately that will only set you up with a new set of negative emotions, from guilt and anger at your own actions. Below is a link which you may find helpful: www.sparkpeople.com/resource/wellness_arti
It is best to find an alternative to do with your hands and mouth - a hobby for the hands (like knitting) and some gum for the mouth if you can't kurb it any other way.
Of course, if you find that you still have problems trying to find an alternative, and this behavior is a common occurrence, then a Therapist can help you to unlock the right tool for you so that you CAN deal with this emotion appropriately.
By the way, it IS o.k. to allow others to see your sadness etc. It is healthy. I find that talking about whatever helps me considerably and keeps me on an even keel, whereas my hubby is inclined to bottle it up and almost get explosive.
