I am so sorry Scarlett, death is always a shock, even when it is expected.
People don't 'get over' death, they weave it into their lives, and it stays forever, but not with the immediate reactions such as random crying.
That's the shock, and as your mind gets used to the idea, the random crying will diminish, and then stop, but don't try and stop it.
Crying is very underestimated, and in western culture it's frowned on, and it shouldn't be, crying is very good for you, so let it come, and run its course, it will help you to get things into focus.
From my experience, there are plenty of good friends on here who will help you, so post when you need, we are always here for you.
