isn't it so hard?

i want to know how people deal with this.. i just made a list of things i need to buy, and ordered the lot online- so chocolate, potato chips, cookies, candy- plus meals, drinks, stuff for the house..

why

i know that chocolate and potato chips and stuff arn't essentials- meals sure, because their's nothing to eat- drinks sure

but why..

i don't understand why i have to order these so called, "essentials", when actually all they do in the end is make you feel guilty
