(((nevagiveup)))) A month is not a long time, hon. You'll need much more time, so much that you shouldn't be thinking about how long it's been. Such a tragedy!
Day by day is how you do this. In those days, make sure that you continue to make your own life feel like it's worth living. Don't dwell on what happened. When those thoughts do overwhelm you, then sit down and give them attention and then...stop. They'll come back again, but you get to control that eventually ok?
You probably have a lot of various emotions inside... and it's important to not let them build up into reactions that you won't like or want to have to apologize for.... talk to someone IRL who can let you work through this. You need support. Don't be hesitant to contact an organization for support either. I think there is a list of them somewhere here.
Everyone mourns eventually.
I'm sorry this person felt they could not deal with whatever feelings they had about life. Hopelessness is a strong feeling.
