look I'm so upset you guys

I pick up so many 12hr shifts for my job I work for Sentara , now here's where I get pissed 😡 so previously my appointment was nov 7th and I just realized my work schedule never changes and I work that day so I text my boss is it possible to get off that day and make it up on my day off she says she can't but can give me the 8th off because we will be over staffed so i called my doctors atleast 4 times through this process however my doctor cannot get me in because first appointment requires ultrasound and 30 min. With doctor they have to make time for the first app. So I'm stuck with being seen on the 14th which I'll be 9 weeks instead of the 7th and have to go to a different location luckily my SO is taking me but this is just crazy this job is just crazy
