I'm so sick and I'm scared I'm gonna die

Hello, I am a 14 year old girl. I had canker sores for about a week, these are usually a prequel to sickness for me. Then I woke up on Monday with a slightly sore throat. On tuesday I woke up with a low fever, muscle aches and that same sore throat but still went to school. Wednesday is when it got really bad, I woke up to get ready for school and my mom took my temperature, I didn't have a fever. So I started to get ready for school. But I noticed that whenever I stood up I felt nauseous. I eventually rushed to the bathroom where I threw up and dry heaved the small amount of food that was in my stomach. My mom agreed that I shouldn't go to school, and she took my temperature one more time before she went to work. It had risen to 101.8. Once she left, I took a long bath hoping it would help me feel better. As soon as I got out of the bath, I threw up again. Then I took a three hour nap, and my fever rose to 103 by the time my mom got home. For the first time all day, she made me eat some saltines, at 1:30pm. Then she gave me some ibouprofen and my fever went down a bit. Throughout the rest of the day I ate less than a full can of chicken noodle soup and some popcicles. I slept well but when I woke up on Thursday I threw up again, and immediately took ibouprofen for my fever. My dad took me to the doctor because they thought I had strep. (My throat was extremely sore and swollen). The doctor told me I didn't have strep. He said it was a virus and would go away soon. Thursday I ate a banana, a chicken salad sandwich, doritos, chick fil a, a milky way, and some popcicles. Friday morning I woke up after sleeping terribly with a white film on the roof of my mouth. When I went to look at it in the mirror, I noticed some white spots on my tonsils. (Which I promptly googled about and had a panic attack) My mom said she would call the doctor and I waited all morning to get a straight answer. They said, "it's just a virus, it'll go away soon. Let us know if the symptoms get worse or if the ibouprofen and tylenol stop working." That morning I ate a smoothie, and my dad made me some eggs for lunch, for dinner I had a casa dia and some popcicles. Around 3pm my fever went to 102 even though I was on ibouprofen and tylenol. My mom called the doctor again and they said to come in tomorrow. I tried to go to sleep Friday night with horrible pains in my stomach like I was going to diarrhea, but couldn't. I only slept for a couple hours before waking up at 1am (Literally praying that it was morning). So that's where I am now, sitting up at 2am writing this. I don't know what to do, I'm so tired but the thought of sleeping is horrible. I'm in so much, constant pain and all the doctors have given me is a strep test and a "It's just a virus, sorry we can't help you" I don't know what to do and I feel so alone and scared. Please help me, someone
