Three Day's without crying all day

Hi all,  Well this has been a step I guess.  I have not cried all day and night now for three days.  Oh I have cried and miss my son so much, but not all day.  Also, I am working on not reliving each moment those last three months he was alive.  Maybe I am making some progress.  This site has helped in so many ways.  I have met so many nice people on here willing to listen.  That within itself is a blessing. But sometime I cry when I don't know that I am going to , like last night I walked in church and there came the tears. But that is okay.  I know my son would not want me to be sad.  I just can't believe he is gone.  Will I ever get to the point to think about him without the horrible pain in my chest.  maybe when I meet him again in Heaven.
My son Kenny was a wonderful wonderful son.  Yes there were things he did I didn't like but he loved me right up to the end.  He mouthed the words love you as his heart stopped.  He was my first born.  We sorta grew up together.  I was barely 17 when he was born.  He has 3 brothers and they are all so fun to be with.  They all have really great jobs and lives.  I live in fear of losing another son hope I don't.
Kenny really showed others his love of God.  Even the day before he left us for Heaven, he could talk (the vent) but was able to convey that he wanted his wife to go pray with the family in the next ICU unit as their family member had passed away.  He thought of others and he knew God can help.  I hope he is enjoying Heaven, well I know he is.  I can't wait till we are all together again when that time comes.
For now, I just keep existing and trying to work through my pain.
