Sometimes I can love others so much that I forget about myself and why I am here. I feel your pain, I have been in that state of misery. My dad is slowly dying and I spend about an hour each day in that misery, it makes us feel empty inside. It is times like these I have to remind myself that God has a reason for giving me this pain. Someday I will understand why. It might be in this life or it might be in the next. But even this daily pain I feel is part of the meaning of life. I haven’t figured it all out yet. I guess that is why life is the journey and heaven is the destination. Sometimes the road is level and sometimes it is an easy coast down a hill. However, quite often it is steep and rocky and difficult to climb. But if we open our hearts and minds to God he will eventually show us that he was with us in these rocky times and these difficulties give as much meaning to our lives as the love does.
