It's only natural that you miss the person. Time will heal the hurt but in the meantime I suggest maybe an increase in your med dose, to take the edge off. Volunteer or get a part time job? Just be with people, any family support? We all go through the fellings of loneliness after breaking up with someone, but we can learn to learn from the situation, even though it hurts. There is someone out there maybe you haven't met them yet!!!!
