It is very hard & now is not the time to be thinking about getting another hamster, some people do find it helps to get another soon after one has gone to the bridge but most wait a while, I know when my first hamster died I really never thought I could bear to go through that again but then after a while when the time is right you find you have a hamster shaped hole in your heart you need to fill, we never replace the ones that have gone before but our hearts grow bigger to let another in.
I agree with Serendipity that having some kind of memorial really helps, if you have a garden making a nice spot you can visit really does make it easier with time, if not a large pot or a memory box can help too.
You will know if or when the time is right for you to have another hamster, for now just cherish the memories & think about the happy times you gave little Halisi.
