Heard the news from a little bird.
First of all, condolences to you and your family for the loss of your mother. You're going through a very hard time, and please, if you feel the need to cry, do so. Let it all out; it's fine not to be okay for the meantime.
Some people like to believe that when people die, they go up to the heavens and become stars. From there, when they look up to the sky, they imagine that person watching over them from above. If it helps, you could believe in the same things, too. c:
Sorry if this message was short, as I've run out of things to say, but I hope this helps.
