What Causes Chronic Vomiting Followed By Hallucination And Headaches?

Hey, I have a question wondering if I was in danger of anything life threatening yesterday. Yesterday morning at 5am I woke up and throwup, then I fell asleep and woke up at 6am and threw up, this cycle continued every 30-60 mins until 7:30, I then went in to my mum s room and I had to lay down there, I threwup in a basin/the toilet every 30-60 mins again until 9, when I wokeup at 9 I went downstairs and was extremely weak and had to lay down on the sofa. I then threwup in a basin every 30 mins and felt extremely sick the WHOLE DAY, at one point I just wanted to die. I tried drinking water but I threwup it, I tried coke and water (my mum went down to the chemist’s and they advised it) then I threw it up too, then I went upstairs again and fell asleep with my electric blanket on for a good hour. Overall I threwup around 20-25 times and ended up throwing up the lining in the stomach (bile) half of the time. My mother said my face was so pale that even my lips were white and I also had an extreme temperature which I felt faintish from. I also had around 10 hallucinations throughout the day and extremely weak limbs, resulting in the inability to even sit up without assistance. I also had quite bad headaches and felt nauseous for the whole day.
