I just accept that life is absurd. Once you accept that morality, your own desires, logic, all of them are like waves through time, coming and going, changing form, never staying still…you recognize how ridiculous it is to desperately cling to any semblence of a ground beneath you. Just let yourself fall into the unknown, and at least the insignificance of your own struggle against the tides of change is acknowledged.
Or you can, y’know, just scream, cry, and rage about it. I think of emotions like a buffet. You gotta try them all at least once, and often in a wide variety of combinations. But hey, you do you.
