I just have to vent

I made it to work this morning with two minutes to spare. I clocked in and started my day... an hour in and I’m in the floor. I fainted and my coworkers gave me water, splashed water on my face, then gave me a can of soup to eat. I told two of my managers what had happened and they said “oh that’s not good” and “oh goodness” and walked out of the room. I ate the soup and still wasn’t feeling too hot. I was scared it was going to happen again, I felt it coming on. So I went to my head manager who was completely oblivious to what just took place and he got upset with me and told me to leave the store. I am now sitting in my car crying hysterically because I’m scared to lose my job before this baby comes. I don’t know what to do, I feel that my and my baby’s health is more important than the three hours I had left to work today yet I can’t stop crying over the fact that I might get fired over this. Mind you, I’m a part time cashier at PetSmart, not a damn real estate agent. pregnancy doesn’t make life hard, people make pregnancy hard.
