I often wonder

I often wonder if I could do more in this situation or that situation. I often wonder how they make a dimond out of coal, or how someone can be so happy all the time, or how a car can drive. There are a lot of I often wonders in the world for me. Today I am asking myself that more then ever. I got a call this morning while I was getting ready for church it was my friends mom. I was a little bit confused as to why her mom would be calling me but I decieded to answer anyway and then came the bad news. My friend had tried to kill herself this morning and she is barley holding on right now. I dont understand, she had a lot of problems in her life but she was always smiling and last night she called me in tears and I talked to her and calmed her down and everything seemed fine she was laughing and making joke towards the end of the phone call. I was getting tired so I told her I was heading to bed and in an upbeat voice she told me "tomorrow everything will be okay" I thought it was weird that she would say that but I didnt think anything of it. How could I have missed this? In her letter she wrote before she did this it says to tell me goodbye and that she loved me dearly and thank you for everything. I wonder if I could have loved her more? If I could have helped her more? I wonder if she knew I was always there for her or was I?
