I'm assuming you have a strong faith in some sort of religion, because otherwise death wouldn't comfort you like that. Personally if I had a loved one who had passed I would want to live forever because atleast I'm garenteed their memory... I HAVE memory, as for what's going to happen after I die? I have no idea. Know what I mean?

I'm not trying to make you feel down, it's just I can bet you any money even if you do see your mom and there is an afterlife of that nature... She would never want to see you, she would want you to live.
