A bit of emptiness

As halloween just passed I couldnt help but look around at all the parents with their smiling children and their laughter which made me think that being a parent is a beautiful thing but I quickly was subdued by emotions of sadness, I miss my son so much! I miss his quirky & random remarks, I miss being able to hug & kiss him & tell him I love him. Since my ex-wife and I split my co-workers also my friends have taken me in and we have become closer friends than ever, they invite me to functions and get togethers, usually if there is a group party I feel overwhelmed with emotion because everyone has a partner and Im the 3rd wheel which sometimes makes me feel like a burden to them. I appreciate everything they've done for me I just dont want to make them feel obligated with anything, maybe I'm just thinking too much on things. Not having anyone tosses some crazy thoughts into my mind and they run rampant up there.I hope to truly be happy one day, with the holidays coming up I dont even want to celebrate. It will be my first holiday without my family and im just wondering how I will take it.
