<human>: Could you distill the essence of the text into 1-3 sentences?

This is my first post, so it's difficult to put this into the correct words so everyone will understand what the hell I'm saying.
I'm working as a sale associate for a multi-million dollar corporation. Sale associate means the dude who is sometimes a cashier but helps stock and does tasks. Since this is my first job I usually work pretty well, I never complain or whine or say I'm tired unlike certain employees. My 2nd boss however has been gossiping with co-workers and complaining that I haven't shown up for a day in the past two weeks. This is due to an allergy infection in my esophagus causing me to vomit anything I eat. I also have Crohn's disease, which is an inflammatory bowel disease and it's a huge bitch to deal with let's just say that. I feel like I'll eventually be fired because of me missing more days since my health is dramatically decreasing (so far I've lost 20lbs since I last weighed myself due to the vomiting) apparently I shouldn't talk to my district or regional manager about this since they themselves won't hear of it and punish me for complaining or even the Human Relations department of the company. The happy part about this is that my 2nd boss is known for doing absolutely nothing, this past Saturday I restocked 4 shelves did a clipboard list of stuff to do from the 2nd boss and also was a cashier while this man sat in the back for the majority of the day. Reddit, I've lurked and seen you guys give knowledgeable answers to terrible situations so I'm hoping you guys could help me out on this one.
<bot>: I may get fired for being a sick worker that works by a man who is healthy and well who does not work.
