What am I supposed to do

OK so like what am I supposed to do with overall life? the act of being alive is so BS, like I have to go to school, so I can get a job and supposedly get a lover, have a kid and then have that kid continue this cycle of infinite life and death with no true meaning or purpose. To be happy means that your brain releases a chemical that makes you happy, what after that. You can only understand what being happy is if there is also sadness but the sadness is overbearing. One last thing have you ever though how a successful marriage means that you either watch your partner die or the watch you die, best case scenario you both die at the same time.
