early leave

So yesterday I started having sharp pains down yonder and feeling a whole bunch of pressure! I called my doctor they told me to go get evaluated . I told my general manager (I am an assistant manager) he said I have to pick up my kids what do you want me to do about it....I said  well my doctor is telling me to go! I'm still feeling a lot of pressure and just plain being uncomfortable. We started getting busy I work in a restaurant. He got mad because I was sitting down . He then asked me to get up and come help . I forced myself to do it and then he dips out!!! Didn't call me all last night !! I'm so over him and this job ! I closed the restaurant early and went home ! Luckily once I showered and put my feet up the pressure stopped being so consistent . My SO is a nurse so he just said if it's consistent by morning we will go get checked ! I just can't believe this place I emailed my supervisor (his boss) no response! This place is a joke
