Right now, times are very difficult. I am finding it hard to keep myself busy and occupied since I am currently unemployed. It's easy to focus on someone when you have time on your hands, and I am assuming you do?

Do you have any distractions? Best advice I can give is to continue to pour yourself into other activities that do not involve thoughts of him -- whatever that may be -- reading, cleaning, walking, talking to friends or family, volunteering your time, writing or journaling, exercising.... anything. Try to put the focus on an activity, then do something else. Keep yourself occupied.
