Time Heals all???

I know that they say that "Time heals all wounds" But I think not. It has been nearly two and a half months since my wife passed away. I guess in the grand scheme of things that isn't a long time. We were married nearly 30 years. Every day the pain of not having her by my side grows stronger. My depression grows deeper. I miss her so much I cry almost every morning and at night. There are days when I just feel like giving up, like I don't want to live anymore. I guess because most of my time was devoted to caring for her because of her disability I feel as if my life has no purpose. Add to that that I also lost my son to the same disease less than a year earlier I feel like God is punishing me for some reason. To take the two most important people in my life from me in such a short period of time just doesn't seem fair. I can't look at her picture or even her clothes without breaking down in tears. I know that there has to be a time for me to clean out her dresser and remove some of her belongings but I just can't even look at most of them right now. I am 54 years old and I am afraid I will spend the rest of my life alone and that scares me half to death> I hate being alone. After all, we were together nearly every day of those 30 wonderful years.
