What went wrong?

As I was cleaning today there was a song on the radio (didn't catch the name) but it said I didn't know how to save a life what went wrong?I lost a friend.To this day I should of called Justin when I didn't hear from him that morning that was a red flag what went wrong? And like the song I lost my son and best friend.I'm still devastated by his death but I know in my heart I have to go on and try to be a better mother for my 2 girls Ashli 19,Rebecca 12.They know my heart is breaking they can tell by my eyes they are so cloudly.Isn't it weird how are moods change from day to day?I was so proud of myself for going to a family gathering and today I feel like shit.What a life I live now.jfm24,Vicki
