How Long Can I Take This?

 At times, I wonder if anyone else in this world suddenly finds themself utterly exhausted for no apparent reason. It baffles me how people can just keep going on, day after day, doing the same old things, taking a shower, eating, going to the bathroom, going to sleep, and repeat it all the next day. Sometimes I just can't help but feel like there is no purpose for any of this. Why should I wake up, brush my teeth, wash my hair, eat my breakfast? What difference does it make? Would it even matter if I just one day decided not to do those things anymore? Just because I'm tired of it all.
