Im 19 Years Old And I Have Been Suffering From

Im 19 years old and I have been suffering from some kind of super scabies. It all started when I was a freshman in high school. I was out with a friend and he was staying with his grandma. we went there to sleep that night. I slept on the floor (which I read that scabies LIVE IN carpeting). I woke up covered head to toe in what looked like hives. My mom said they were hives and she's an RN. I've been itchy ever since. Always feel like bugs are crawling on me, I get these really weird looking rashes that look like lesions randomly, literally every inch of my body. It was just brought to my attention recently because a friend said he was diagnosed with them. I must have infected him. I have every symptom. All the rashes in all the spots, dry flaky skin, discoloration, fatigue, hearing loss, lightheadedness, joint pains, my organs hurt sometimes. I know that if I disinfect myself I'll be reinfected. They are at home and on everyone I know and care about. I'm contiplating suicide. HELP
