Oh my Kourtney.....I am just now reading this.......and it's breaking my heart.
I am so very sorry, and please read and re-read these posts, some of them have very good advice and day by day the shock will lessen and be replaced by something else, I know I lost my Mom suddenly and unexpectedly, and honestly whether a person takes their own life or if they leave us in another way, it all causes stress, anger, grief, so many emotions, and each person deals with them in a different manner and they may come to each person in a different order even. Grief counseling would be a very good thing to look into, or another support group, just remember you are not alone in all of this.
Please do not try to figure out "why", I know that question will be looming, but please remember you have your family and you all need to support each other, in whatever way that is. Again, each person needs different levels of comforting.......
Hugs sweetie, I sure wish I could take away the pain.
