Dalgon,
Firstly may I say how sorry I am for this loss, and how awful you must be feeling emotionally right now.
I also was in a car crash my fiance was driving with my children in the back. I lost my rock, my love, my wonderful loving fiance of 8 years. This was five years ago almost.
I hope you have a good support system in place with friends and family and good doctors to support you through this time.
I went through such high intensity of emotions, and I expect you are too. The what if's what if I hadn't gone out that day. What if that strange day....The brain can take you to some weird places. I'm sure you will explore them sticking at times with things.
I found drawing very helpful to draw what I felt and to try and label a word for what I was feeling. for me there was also the funerals my fiances birthday and Christmas and New year all with in a month of the crash.
I also have a co worker who lost her 17 year old driving and she went through anger at why her son had drove his car so fast and was angry at him for losing him and her loss, grief etc.
any time I can be a listening ear, or you want to vent your feelings you just do that.
