I usually give the same advice on this topic to friends/strangers...get a hobby, go out with friends, find a book/library card, sew a new skirt, do anything that makes the time go by. Eventually, it will be easier. Just wake up each morning, make a plan, stick to it, and, btw, don't forget to breathe...it will be ok before you know it. Soon you will not be thinking of him all the time. Finding things to fill your days and nights is the answer. Trust me. I have been there!
