You don't have to fear, you don't have to feel loss, you don't have to suffer.
Realizing emptiness is what we're here for. It is the prime objective, it's our goal. All these other things we do are to either accomplish wisdom realizing emptiness or to comprehend and relinquish feeding.
Human lives are short, our bodies are frail. There's a limited amount of effort we can sustain as humans, fortunately wisdom realizing emptiness is far below that limit. If people can exert a lifetime of effort working towards pathetic aims like a beautiful body or possessions, surely we can put a little effort into ending all our grief with wisdom realizing emptiness.
Study, study, study. As Westerners we've been exposed to a lot of ridiculous hype about "emptiness" and it takes regular study just to correct the brainwashing of our societies that would have us thinking with tv show logic.
Then it takes work to realized. Fortunately, if you are practicing sadhanas, a portion of the generation is that work. It is not listed in many(maybe most) sadhanas, either because the writers thought Westerners either knew already or were too stupid, but in the generation of a deity there should be a line starting with, "Om Sobhava Shuddoh", and this is where you use reasoning like dependent arising and four point analysis to see the emptiness of particular objects and then objects in general. It's a skill you develop, like taking apart and diffusing a bomb. And when you have seen the emptiness of a particular object of that phantom false appearance of it as inherently real, you say the mantra starting with "Om Sobhava" as a confirmation of sorts.
Obviously you cannot do this essential part of the sadhana correctly without learning the reasonings and clearing away the notions of emptiness taught to you by the ninja turtles or 365 days of Zen dogs calendars.
