I have those every other week, not a big deal to me anymore.
When we die we go back into the universe, similar to the state before we were born, and everything will be....peaceful again. Who cares about being remembered? You will be dead and NOTHING, your love, your current, past, or future feelings, family, experiences won't matter. Maybe they will to those still alive, but they will die too.
What to do about it? Don't care about it.
