I just need to go on a rant.

I worked 4-midnight last night, and that shift is really hard on me, since I'm so tired, I'm a danger on the road to other drivers because I swerve and try and control it bit I don't do a good job, so I rolled down the windows while it's 35 degrees outside, blast the A/C and my music to keep me awake and alert. I got home wemt to bed right away woke up today at 10, my work calls at 10:30 I didn't answer it at first because I had just thought "shit I think I left my wallet at work" anyways I missed the call and called back right away, and they had asked if I wanted to work from 10:30-6:30 and I told them yes but I won't get there until late that I had just woken up, they were fine with that and got there at 11 so I was getting off at 7. Well the scheduling manager didn't schedule enough baggers or checkers for the night shift two checkers and no baggers! Lines were backed up going as fast as we can. 7 had hit and it's still crazy busy, they asked me to stay and I agreed, only if I got another break since I had only gotten one break that whole day and and we only get 10 minute breaks. And I had explained this my whole 8 hour shift I had only gotten one break I hurt, my Braxton hicks are going I have a pinched nerve that I've had to stand on all day, had a pretty bad Charlie horse and the only reason that I woke up, and they acted as if I was asking for a lot just to get another 10 minute break out of my 9 hour day. Twisting my whole upper body all day makes you hurt especially at 30 weeks pregnant. I'm a cashier so I just stand in one spot all day. But the whole last hour of my shift they just acted as if I was being selfish, for demanding that I got a second break. I'm truly happy that I didn't have to close again tonight, but I'm irratated of the fact that I went the whole day accepting that I only get one break out of my 8 hour shift. But when I was asked to stay until 8 and told them I only will if they give me another break they acted like it was a big deal. And then I come home and my parents want me to do this this and this. And I got to yelled at for saying no when I hurt and all I want to do is relax. I just feel like I pulled a double shift, with closing yesterday and coming back in all day today. And no one gets that my feet hurt, my bad hurts, my hips hurt and Braxton hicks are just kicking my ass right now. And no one cares. They think "Oh get over it" maybe I'm overreacting but I feel like I was appreciated at work at all today and get home and people demand that I do things and wash up the dishes that I didn't even touch.
