I feel what you're going through. Loss is a tough thing to cope with, but truthfully, all I do is do things to take your mind off of it. Don't go into a relationship with someone else, because then you'll be stuck in something you probably don't want to be in. Spend time with your family, eat things you love, and do things you love that require physical activity, don't let they're memory bring sadness into you. Take that memory and use it for good, and bring happiness into your own life.
