You can die from loneliness. It will not be a sudden death but your immunity will be very weak so you can easily acquire diseases. Don't allow yourself to drown in loneliness. While you still have a little strength left, try to list down things you want to buy and places you want to visit. Show up prepared in every event. You will only get lonelier if you get remembered as a lonely lady who is a bit unkempt. Try buying some new dress if you feel nothing seems to work anymore. I am sure you can find something that fits your loneliness elegantly.
All my life I waited for someone to teach me things I will never learn in school. Now that I am in front of these people, I don't understand why I waste my time crying when I should be busy working. I need to spend more time with the right people who also value my presence. I feel terrible when I can't get any work done. I feel worse when I let people down or when I mess up their schedule. I am not sure why I am talking about this. I notice that this new found negativity is already taking the toll on my health.
