Her diarrhea was constant for about two months after her first vaccine. She feels like she was dying, she was desperate to find out what was going on with her and find out how to get it to stop. She had chills and hot flashes and sweating along with diarrhea, a combination of symptoms, that are relentless. She feels like she was melting from the inside out. She did not have a fever, she takes her temperature, but her core body temperature felt like she has got a furnace inside her. She burns and burns, it was hot , so she stops and lays down in front of the AC then she gets cold and covers up because she was feeling chilly. After a certain length of time she overheats. She clarifies her phrase about feeling like she was dying by saying that she feels like she wants to die because she wants it to stop. She feels depressed and hopeless, it affects her in a lot of ways, physically and emotionally. She has been taking Imodium to stop the diarrhea.
