<human>: So first off, I'm a long time lurker of this sub reddit, first time poster. So I am a new worker at a convenient store, I've been working for about 2 weeks,  my boss told me 3 days ago I am going to have 2 days off, after those 2 days, my shift will be from 6 am to 2 pm until further notice. Today is Monday and I am here at 6 am like she instructed, and I am super tired, so I grab a small breakfast sand which and a monster because like I said I need energy. So now I'm all hopped up on energy and ready to work. Here comes my boss strolling in from her daily commute, she comes in looks at me weird and says "Are you working today?" And I said "Yes you told me to come in at 6 am to 2 pm." She tells me she has me marked on the work schedule from 2 pm to 10 pm instead (she never showed me this schedule or where it was so there was no way of me checking myself.) So now I'm stuck at home with a butt load of energy so I can't nap until my shift like I want to, and by the time my shift rolls in the sugar crash will already be here and I'll be sluggish. (Don't have enough to buy another Monster.)

Can you condense the text into three sentences or less?
<bot>: Thought my shift was at 6 am, tired af, took energy drink, told I was to come later on when the crash hits. Today is going to be great..
