Overcoming the pain of death
A solution which, by definition, most people do not want (because that very desire is what's being attacked). The solution might sound bleak, but it really does provide levity, relief and insight.
The thought of your own death produces a deep melancholy. You pity yourself, your efforts, the high hopes which characterised your youth, your striving for a nice life, and so on. The failure to attain this fills you with a sense of deep shame and error, and your life feels like it was for nothing. Things did not last, they did not turn out as you expected. Your life, being the most valuable thing to you, suffers a serious loss of esteem. This is an enormous humiliation and levelling-down. Upon first realising it, it is a most agonising and stomach-wrenching feeling.
